I have 20$ of bitcoin. What should i do with it instead of spending all.Tell me Pls.

I am new too. I can give you a tip. If you need money, then sell it. If you want to get good profits, keep your bitcoin yourself and buy more bitcoins. Because Bitcoin prices are going down for a few months, it is expected that Bitcoin prices will increase in the next month. Keep your Bitcoin close to you now. When prices rise, you get good profits.
