There's nothing wrong with speculating in crypto with a small % of your net worth. Same as any very volatile speculative investment. Your problem is that you threw money into something having done zero research for yourself to learn about it first, I'm assuming hoping it would 10x+ in price. The good news is that your $150 wasn't going to give you much of a return anywhere, so if you want to sell it or keep it, it really doesn't matter much tbh. But you should take this lesson about doing proper research in the future before putting money into something. It's not too late to read and learn a bunch now either.
