yeah, the bot is not that quick (depending on strategy). but no, this will lead to very quick capital tie down. it will possibly take weeks to sell at profit. which is fine, if you have a lot of capital to play with, because eventually almost every coin bounces back. but is it painful looking for a month at a bought coin which climbed back, but lingers in the minus 2 to 5% band and can't get higher. and with time these coins can multiply very fast.
