Honestly, if you can consistently make 10-20% monthly profit thats crazy gains Definitely not easy to do.

Try looking into arbitraging perhaps? Usually lower return since market is competitive now, but also the risk is lower. On some good months you can probably make 5% or more

Everybody thinks he's too late.

Those who bought at 100 regret why they didn't buy at 10, who bought at 1000 regret why they didn't buy at 100, and so on.

Look forward my friend, why not think more about what you should do now rather than regretting the past
