Advice needed regarding BTC and making a profit

Honestly, I don't really know what I'm doing. I brought some BTC before the big crash, at 42, 000 GBP and I've held onto it. . Now, it's looking like there's a chance I can make my money back and I'm pretty pumped. I'm even thinking about risking it and making some money. What is the best way for me to do this? I've heard of day trading but I'm not really sure how it works. . Sorry for being such a noob, I'm sure everyone is suck and tired of people asking these questions ???? I would really appreciate any advice you can give to me! .............................................
