Like what? What it can offer more? Crypto signals didn't help traders to cut losses but only giving a stop loss (Which is mandatory to all trades), manage their capital? I don't think so, they only give signals and did not advice each user or consult them what to do with their capital and how much they will use in trade.

About your last bullet "how to change and set targets to make as much profit as possible." just because you change strategy or targets doesn't mean you will going to profit as much as possible since trading needs patience not unless you are going to trade in 1 minute chart.
