It Started with Scammers

I was contacted a few months ago about a great job opportunity that pays 8k / month in crypto ???? needless to say, I knew what they were up to. I took advantage of a few small payouts then quit my job(s) ????. During the most recent attempt (July), I realized that if rather than withdrawing my crypto that I was ‘’paid’ in during April, if I had left it in my account - I would have made a lot more money. I am now depositing $50 on a semi-regular basis and hoping to grow to 1 BTC (while also avoiding scammers). Any advice for a beginner? Specifically, at what point do I leave Coinbase, I see people saying it is a terrible platform, but good for beginners. When do I switch platforms, and how?

I’ve been good at buying whenever it dips. Currently I am at a small loss but see this as a good long term investment.
