Hello
I do think that no matter how reliable a person is , when it comes to bitcoins and other cryptocurrencies it takes a second to loose all your coins. Not your keys, not your coins man ! Just see the price right now , it's climbing, just encash after a while and buy when the price goes low. You have to invest time there yourself. The whole idea behind these decentralized exchanges is ****to make sure people take their own financial decisions****, it's really risky and I don't think you should do that , you can lend your coins but then again I won't recommend it. There are some wallets giving people some interest and such , search it out and see if you like it but I would suggest you to *" NEVER give your bitcoins to someone"* even though it's a trusted booker.
You can take some free crash courses on the internet also about the trading. At the same time there are trading platforms giving advices and such for free. Just be thorough with the news and give it time to mature.
