You can start up with any amount you have to invest, it must not be something too large . If you are thinking what you have is too small can be time delaying. Cut your coat According to size and do not look down on the little you have. Go ahead and invest if you really want. Your first move matters alot.

General questions that can be explained by all members here.
I'm sure everyone has a different opinion. Starting to invest in crypto is very easy and the minimum initial investment depends on where you start. Binance, Coinbase or cashapp you mentioned.
Don't think about how much capital you should have, but first learn how to trade in crypto. Do not let you enter without trading knowledge. it will waste your money.

The rest you can read some threads that you can find in this forum.
