Best app for keeping track of portfolio? I've been trying to find a good Android app that would automatically synch with my exchanges and provide me with information (in real time) such as current balance, percent chance of portfolio, total gain/loss, as well as last change, equity, percent change, total gain/loss, total percent change (since entering portfolio) and average purchase cost of each coin individually (in USD, ETH, and BTC at least). I've been using Robinhood for the past year while trading stocks and I'm kind of surprised that there doesn't appear to be a similar app for crypto that is as clean, intuitive, and comprehensive. I've tried Blockfolio, Delta, Crypto Tracker, and now on Cryptoport. I don't want to have to input everything by hand, but it's nice (tho not necessary) to have the option. And I wish the apps would automatically subtract trading fees to give the correct end balance depending on the exchange. http://ift.tt/2CmWTO3

How does SegWit reduce transaction size, when the signature is simply moved to another part of the transaction? This video explains that the signature is moved out of the input section and moved to the new one called the witness. From what I can tell, the witness signature is still contained in this transaction - how would a simple reordering of information magically create more space? I've perused other articles and videos and none of them seem to address this "magic". http://ift.tt/2C3bhrk

Were one or more machines required to be running 24/7 on the network after the first block was mined? After mining the genesis block, did Satochi have to leave his computer running to mine the subsequente empty blocks? Was he running the whole network on a single node or did he require multiple nodes to test the transaction verifications? What would happen if at some point all nodes were off and no transactions or blocks were being generated? At some point the whole net work were probably a couple of personal computers. Did they run 24/7? http://ift.tt/2C3sTTD

Bitcoin Mixing? Is it even real? I have been trying to find a "bitcoin mixing" service but it seems that ALL the "bitcoin mixing" sites I have looked at are scam. Does anybody know of any that are actually real and do what they say they do?? http://ift.tt/2Ctx0vK

Convert P2SH to P2PKH I'm using btcrecover to recover a Ledger BIP39 backup seed that I wrote down but seems to be wrong. The tool only accepts P2PKH addresses and my account was created very recently in this kind of format 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy. I'm new to blockchain but I believe that this is a Segwit/P2SH account? Is there a way I can convert this into a P2PKH address so that I can use the tool? http://ift.tt/2C5cMFf

So I mined a block, but why would other nodes accept my mined block? When a miner finds a hash and is thus able to confirm a block of transactions, that miner will then broadcast the confirmation (block?) to the other Bitcoin nodes so taht it can be added to the blockchain. My question is, what is the incentive for teh other nodes to accept this mined block, even if it is correct and checks out against older blocks? I ask because if the reward for mining blocks decreases over time, other nodes may selfishly not want to accept this miner's effort and prefer to figure it out on their own for a greater reward now than later. http://ift.tt/2C1z36J
