The reason why the rich become rich is because sometimes they can see opportunities that we can’t see. Although you missed Bitcoin when you were a student, there are still many cryptocurrencies to choose from. Sushi is a good opportunity.
Not really, some of us who is poor could see opportunities but doesn't have enough wealth to pour good amount of money to that specific investment (Bitcoin for example), or It could be poor people doesn't have enough risk tolerance thinking about how limited their wealth is. Perfect example is the OP, necessities pushes them to sell their Btc early while the price was down. These young men sees opportunity in Bitcoin typically not everyone in their younger years.
Sad reality is that, rich people could easily make more money than the poor people.
