I've studied most Bitcoin investors, those who have money to invest are the ones going around looking for someone to teach them how to invest, the first thing they want to learn is how to use the exchange to make purchases using Fiat on the exchange, they are always in hurry, they have no time.
Those who don't have money, have all the time to keep learning and reading stuff online about Bitcoin and the crypto space, they have no reason to be in any hurry and it seems they are the ones that avoid the unnecessary dramas in the crypto space because they took their time to learn first.
Do not walk away from Bitcoin investment because you don't have the money, it's even better not to have money because you will have the patience to learn more about everything, and when the money comes, you will be able to avoid many dramas.
How come it is better to have no money to invest in Bitcoin? I mean, you need money to invest in bitcoin. I get what you are trying to say. That if you have no money, at least you will try to learn about crypto currencies and the market, but lets be honest over here. If you never actually invest in crypto currencies, you won't really be learning anything. Reading from lots of books, articles, watching videos and trading on demo platform might help you a little, but as long as you don't get real experience, you haven't really learnt much.
