I liken safe to expensive.

Expensive for you is probably not the same as pricey for me. (Do not take that as me saying I've more or do not have more - which actually isn't the point.)

Safe for you is probably not the same as safe for me.

My personal opinion on the thing is to begin with looking to achieve .25 percent per day. If the yield you suggest is the equivalent of sitting at a table and eating an whole elephant and will cause you to achieve your sense of succeeding out of trading, there is no shame in beginning smaller to see what may or may not work to achieve that objective.
