What you are describing is called Arbitrage and is done by many traders for a variety of different assets, not just cryptocurrencies. This is only guaranteed to make you money so long as there is a price difference between exchanges. The end result of many people doing arbitrage is that the exchanges all settle onto the same price. The main difficulty in ...

Option 1 I'm not sure on which platform you are, but if you use a Linux or Mac, you can combine the following two commands (sources here and here. Check also the at manual): echo "ls -l" | at 07:00 and bitcoind sendtoaddress <bitcoinaddress> <amount> to make something like: echo "bitcoind sendtoaddress ...

Quandl has many bitcoin data sets. Here is a collections page of them. On top of that , it has almost any other time series data you can imagine: Everything from Stocks, fundamentals to diabetes and fertility rates. What I love is that there is one easy API to access all of this data, so it is very easy to cross-compare the data sets There's also an ...

Every output of a transaction needs to be explicitly spent as an input eventually, but there is no need to stage deposits separately and resend them to yourself again.

What goes wrong is that you make a profit on every trade, but you are holding lots of bitcoin when it goes down and lots of whatevercoin when it goes down.

I'd say that's just because nobody programmed it. Bisq community for example is short on programmers so they concentrate on the essentials. Companies have no interest in the development or shy away from the legal risk, where they are increasingly forced to perform financial police duties similar like banks (KYC/AML). Hopefully the Bisq DAO brings enough ...

Use regtest, the regression testing network, not testnet. Results using it are reliable and repeatable, most importantly don’t rely on the will of others.

Generally, the exchange will use a full node that is continuously checking the network for received transactions. Once it detects a transaction has been made to your deposit address it waits for the transaction to be confirmed, then it will credit you the balance. This data is stored in a private database managed by the exchange where they keep track of each ...
