To be rich we need no coins that is at 1 satoshi or very cheap coins, you should easily be rich with high market cap coins but you should be lucky and wise for that.
1 Satoshi? Well,I think that amount is quite small but if you have lots of it then there is a tendency that you will become rich. To become rich is impossible especially if there is a requirement for you to become one. If it is not a requirement then there is no need to rush. And,I think patience is always the main source to achieve that.
I think what is really needed is to know what you are venturing first, the money is there whatever you are doing try to master your craft and those things you don't know inn order for you to quantify and weigh things. I believe that's the secret of becoming rich as per the rich people i know.
