My most recommend way is bot trading i've never tried it but also going to try and make it. I've seen some videos of it that really quite catch my interest especially when i am lawsy trader and it doesn't just trade for you and provide automation it also gives you profit by trading without any emotions attach. As long as the bot is properly coded and properly tested, i think there should be no problems with this.
There are some platforms out there that let you 'make your own bot', quite useful without having to design the whole thing from scratch
You need to know how to set it up, and you need to have a bankroll for that trading bot to work. It can be a problem to set it up, it can be a problem if you don't have the required amount, and all that time you are risking, for holding your coins on the exchange and for a trading bot. Risks are huge, I'm not sure about the profit someone can make with some small amounts.
