Well, you can invest 10$ in some coin and still profit on trading but the profit is miniscule. You can definitely start with small amount but the profit os directly proportional tp it
in my opinion, we can invest from little by little if there is no result we will not be disappointed a lot. the problem is that we are beginners if we invest a lot if we fail it makes us disappointed.
how to make our money growth is more important for us.investing with big amount without any skill could make our money loss if something wrong happen to market.
