Other things to keep in mind are the fees that are all over the place. There are a few exchanges that have coins that are not available on the others, in order to make money trading those coins, we have to beat out the trading fees and still have enough of a mainstream coin to withdraw and have made money. These can kick your butt, many small traders jump on a 100 Sat difference in price and give that money right back to the exchange in the fees here and there.
