Update Poloniex prices\n>function updatePoloniex() \n >{ \n >  var response = UrlFetchApp.fetch(\"https://poloniex.com/public?command=returnTicker\"); \n >  // TODO: set your sheet name here \n >  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(\"Coins\"); \n >  var json = JSON.parse(response.getContentText()); \n >  var rateeth = json.BTC_ETH.last; \n >  var rateetc = json.BTC_ETC.last; \n\n >  // TODO: set column coordinates here in format (column, row); this is now set to A2 , B2\n >  sheet.getRange(2, 1).setValue(rateeth); \n >  sheet.getRange(2, 2).setValue(rateetc); \n\n >} \n\n# 2. Update Bittrex prices (I not programmer so I do my way :) )\nI create one more sheet to get the result from Bittrex API return and use Excel command to get the last price\na. Get the API result  with  this function\n\n>function updateBittrex() \n >{ \n >  var responseltc = UrlFetchApp.fetch(\"https://bittrex.com/api/v1.1/public/getmarketsummary?market=btc-ltc\"); \n  >  // TODO: set your sheet name from your new Sheet here \n >  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(\"BTC\"); \n >  // TODO: set column coordinates here in format (column, row); this is now set to A2 \n >  sheet.getRange(2, 1).setValue(responsltc); \n >} \n\nb. Get the price\nI get the LTC price with command below, replace *BTC!* with your Sheet name\n>=LEFT((LEFT(RIGHT(BTC!A2,LEN(BTC!A2)-(SEARCH(\"last\",BTC!A2,\"1\")+5)),10)),SEARCH(\",\",(LEFT(RIGHT(BTC!A2,LEN(BTC!A2)-(SEARCH(\"last\",BTC!A2,\"1\")+5)),14)),\"1\")-1)\n\n# 3. Update BTC-e prices \nThe same way with Bittrex but replace \n>https://bittrex.com/api/v1.1/public/getmarketsummary?market=btc-ltc\n\nwith \n\n>https://btc-e.com/api/2/btc_usd/ticker\n\n# 4. Last step\nThis step will tell you how to update Sheets every 1 minute or manual update\nThis function will create a menu for you manual update Poloniex, BTC-e or update all\n>function onOpen() { \n >  var sheet = SpreadsheetApp.getActiveSpreadsheet(); \n >  var entries = [{ \n >    name : \"Update Poloniex rate\", \n >    functionName : \"updatePoloniex\" \n >  }, { \n >    name : \"Update BTCe rate\", \n >    functionName : \"updateBTCe\" \n >  }, { \n >    name : \"Update all\", \n >    functionName : \"updateAll\" \n >  }]; \n >  sheet.addMenu(\"Scripts\", entries); \n >}; \n\nIf you want auto update price every one minute, from Script editor, select Edit then Current project's triggers, click *\t\nNo triggers set up. Click here to add one now.* to create new one\n![auto.png](https://steemitimages.com/DQmcaWSeVjSB8cRYbVBdumc3gGdc1UpxR3F2rwu8Pbu3M9U/auto.png)\n\nYou can see demo here: https://docs.google.com/spreadsheets/d/1hIVEOdUQzP5JsYtuzR-MNdapV3ByxyBw9HLlXJK4l2c/edit?usp=sharing",

      "body": "http://cryptomining-blog.com/wp-content/uploads/2017/05/coindata-main.jpg\nPumps and Dumps in the crypto world are something we are often seeing happening only only with more established and popular coins, but also with crypto coins that you may not have even heard of. We are not big fans of actions like these as they are used to help some people make even more money out of unsuspecting users. Normally regular users have absolutely no idea when and what a pump and dump may happen, so they can hardly profit from them, but what if you can join and make some profit as well? Here comes CoinData, a cliometric based trading tool that tracks trading volumes on the exchanges and helps you signal when a pump and dump might happen. With it you can see the whales’ trading intentions through the volume they trade: buy / sell walls appearing / disappearing, preparing to pump or dump the actual coin you trade.\nhttp://cryptomining-blog.com/wp-content/uploads/2017/05/coindata-notifications.jpg\nYou can track trading volumes or crypto coins or buy walls appearing manually, but tracking even a few of the top coins on a single exchange might be hard enough, let alone doing it for all and on multiple exchanges. That is where CoinData comes with help by giving you up to date information on all coins traded on Poloniex and Bittrex (for the moment) and giving you signals when a coin is probably going to be pumped up or dumped, so you can make the right move and buy or sell. The service also reports on when a buy wall appears as this is usually a sign that a pump can soon be happening, making the coin interesting to monitor. To make things easier you even get real time notifications to help you keep track of what is happening when you are not watching the tables with trading data.\n\nDo note that the service provided by CoinData is not available for free, there is a subscription fee that you need to pay in order to access real time data. There is a 1 day and 10 days trials available to try out the service as well as 30 days and 60 days regular subscription available should you decide to keep using the service after you try it out. We are currently testing it and so far our initial results are more positive than negative. Be wary that some of the signals you get may not turn out to be real pump and dump and sometimes you might still end up losing instead of winning by getting into the game, so be careful should you decide to get in with larger sums. On the other hand if you trade with too little coins, then the subscription fee you pay for the service might not be worth it if you are unable to profit enough to even cover it.\nhttp://cryptomining-blog.com/wp-content/uploads/2017/05/coindata-subscription-580x530.jpg\n\nIf you want to sign up to coindata.io, you can use my affiliate link if you want: https://coindata.io/welcome/r/LAKP-L75915",

      "body": "https://media.coindesk.com/uploads/2017/05/shutterstock_84338188.jpg\n\nEthereum supporters have every reason to be elated.\n\nNot only has the value of the platform's ether tokens jumped by about 900% since the start of the year, but the public blockchain has recently attracted attention from banks and tech behemoths. And while ethereum supporters have long argued that the global computing platform would help to form a new kind of internet, a wave of innovators are now trying to deliver on that ideal.\n\nThe problem is that there might be downsides to this increase in price and increase in attention. Namely, as the price increases, ethereum apps grow more expensive to use.\n\nThat's because on ethereum, users need to pay directly for the computational power they use, whether to place a bid on a prediction market or use new kinds of decentralized Twitters and Ubers. For now, this is a different picture than, say, Facebook, the popularity of which rests in part on its 'free' platform.\n\nMatus Lestan, co-founder of the ethereum app Ethlance, for example, recently posted a screenshot of a user looking to create a user profile on the platform – an action that cost 0.08 ETH, or $7. It would have cost \"little more than $1\" when ether was at $10, he wrote.\n\nGiven this increase, Luis Cuende, project lead at decentralized startup Aragon, told CoinDesk:\n\n    \"[I]t's very understandable that some users may be pissed off.\"\n\nThe price of gas\n\nStill, many ethereum apps, including Aragon, are in the test stage right now. So, it's unclear how many apps and users are actually impacted by this increase.\n\nIt might be more of a harbinger of future friction. Augur co-founder Joey Krug, for instance, said that users of his ethereum-based platform aren't being impacted.\n\n\"Since Augur is currently still in beta on testnet [the higher prices haven't] affected us directly yet,\" he said. \"However, once it's live, it will indeed.\"\n\nAdding to the complexity, though, is that the prices are more dynamic than simply being affected by the cryptocurrency's increase in value.\n\nThe details are a bit thorny. First off, it's worth noting that 'gas', 'gas price' and 'gas cost' all mean different things. (Even ethereum's inventor has mixed up the terms.)\n\n'Gas' describes units of computational power in ethereum, while 'gas cost' is used to denote how much gas is required to perform an action on the platform. A simple transaction costs 500 gas, while storing data using ethereum costs 100 gas.\n\nThese numbers are hardcoded into the software. Finally, the 'gas price' is how much each unit of gas costs in ether.\n\nThe total cost of an action on ethereum is the gas cost multiplied by the gas price. If the gas price stays the same while the value of ether increases, as has been the case so far, then the overall price of smart contracts increases.\n\nIn ethereum, miners set these gas prices. \"Miners are the ones calling the shots,\" Jason Teutsch, founder of scalability project TrueBit Foundation, told CoinDesk.\nMiner pressure\n\nSome expect that miners will lower the gas prices. Their incentive to do so, one argument goes, is that if they don't, less people will use the network and pay transaction fees. So far, though, this hasn't happened.\n\nThe gas price sometimes fluctuates, according to a chart from ethereum data site Etherscan, but has stayed at roughly the 22 to 23 Gwei range (0.000000000000000022 ETH or less than 1 cent) for the past year.\n\n\"It's a bit of mystery to me why this quantity remains so stable. Perhaps it's an artifact of mining pool policies, but it might also reflect some average fixed cost perceived by miners,\" Teutsch said.\n\nSo, the situation could be mitigated if miners pushed down fees. Indeed, some users are currently campaigning mining pools to push down the gas prices.\n\nAdding to the confusion, as Krug pointed out, is that users can post transactions with a fee that's less than this hardcoded price. Transactions might not go through as quickly, but he pointed out that, even at about one-twentieth of the current price, \"it's really not much slower\". The problem is that most users are simply going along with the hardcoded price.\n\nGiven this, there might be less reason to worry about an increase in prices just yet. Because blocks aren't full, in fact many of them are empty, users aren't fighting to get their transactions into a block with increased fees (as with bitcoin).\n\n\"Gas prices aren't going down, but blocks aren't being filled either, it's a lose-lose all around,\" Krug said.\n\n\"A large amount of this is due to developer failure to act,\" he said, arguing that developers should introduce a more dynamic gas price that is dependent, in part, on how full blocks are.\n\nLonger term, there are other limitations to public blockchain technologies as they stand today. For example, there's a limit on the amount of computational power per block on ethereum. This limit is roughly equivalent to bitcoin's block size, although ethereum miners, again, can increase or decrease it.\n\nWouldn't it be simple to just reduce the gas prices while also increasing the amount of gas that fits into a block? Well, there are trade-offs: increasing the gas limit increases the burden of running an ethereum full node.\n\nDealing with these trade-offs is a problem bitcoin has also faced. And is, in a sense, a big element of its block size debate is centered on the community arguing about growing transaction fees.\n\nIn other words, a lower gas limit is required for ethereum to remain decentralized. But that could lead to higher smart contract prices in the long term, as more people use the platform.\nTowards solutions?\n\nIn that way, you could think of these price increases as a symptom of blockchain tech's larger scalability problems, of which there are a range of projects that might help.\n\nOne such project is TrueBit, which pushes ethereum smart contract computation verification, such as more advanced computations like machine learning, to a new layer above the blockchain.\n\n\"TrueBit is immune to some of these problems,\" Teutsch said, arguing that the platform can help with transaction throughput, as well as facilitate more advanced ethereum computations.\n\nWhat does that mean in this situation? The idea is that then you don't have to settle as many computations directly on the blockchain. You'll still have to pay fees to the computers in the TrueBit market, but the idea is that you will rarely have to pay the more expensive fees required to settle a transaction on-chain.\n\nGilles Fedak, co-founder of distributed cloud computing app IEx.ec, noted that although their applications are already primarily off-chain, the team behind the computing platform is looking to another off-chain network, Raiden, to help with some of their problems.\n\nIn another direction, Cuende said that Aragon's business model might be an inspiration for other decentralized apps. The startup plans to pay transaction fees on the platform, shielding users from the increasing prices.\n\nStill, all of these projects are works in progress. And until they come to fruition, or miners adopt new fee structures, ethereum smart contract fees could climb. Which is a little ironic, considering Buterin once suggested that bitcoin's transaction fees are too high.\n\nSource: https://goo.gl/RvC3Ba",
