Before someone does this, the person needs to do a lot of research because if the person does not do much research can run the risk of correctors to profit from the person, that is, the correctors can take advantage of the person's ingenuity. This is bad, My opinion would be that exchanges like coinbase, Cex, coinmama, Bitpanda and others would be more appropriate, as long as the person does not make the mistake like this:

The person has $1000 and wants to buy bitcoin and it takes $ 1000 to buy bitcoin, the idea is buy by parts and at different websites to prevent the risk of being stolen or cheated.
