If you plan to indeed trade, maybe let some bots do the job after you know how to fine tune them.

Or, just leave trading and HODL. Trading is not for everybody, you know. For me, some years ago, one simple way to ensure that fear won't make me sell early was the paper wallet: until you get to the point you'd sweep the paper wallet you may get to your senses, understand why you made the paper wallet, and stop doing the stupid thing. But this works only when HODLing.
