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.
