Being patient is key but it is not the only thing, many people do think that is enough and that is not true, you need also to get as much knowledge as you can so you can invest in icos or small cap altcoins, if you are able to become good enough at that then you are going to become rich without a doubt even if your starting capital is very small, it will take some time but it is completely worth it however if you go that route you also need to understand and accept that you can lose all your money.
