How much % of net profit is good?

I know it is a very difficult question, as volatility and prices vary considerably. But as a not-pro trader, I don’t kno what to think on my actual performance on a one-year span. Is 10% good? Is 20% good? Is 50% good? At what point do you consider that an amateur is doing well? (without being at the same level as a pro, and considering I « work » on cryptos about 15minutes a day)
