I really like the first post of this thread

You see already 2015 there were alot of people who believed in bitcoin and tell everbody to hodl! These people are rich today. You d everything right!

But... are they still hodling? Some not: they have cashed out.
They are rich now.
Lol, that there are people telling others to hold their bitcoin back in 2015 doesnt mean that theyre rich now. Some of these people telling others to hold back in 2015 are even the worst when it comes to panicking, and the op can possibly be one of them. By the way, this is Investment, if you think you have made a lot of money, then you should make space for others to invest and make their own.
Those that want to make money in this space will need to take risks in the same way the early adopters did back in the day, you cannot buy bitcoin and become rich overnight anymore, you will need to look for altcoins with low market cap that have honest developers and good ideas.
