They were very lucky and they had already made a huge profit from what they collected. if only I had invested in Bitcoin when it was first launched back in 2009, the profits I could earn today could reach millions or billions of dollars. Crypto does not only have the potential to provide huge profits, but also big losses. However, there are many success stories around bitcoin investing out there that are just like them or beyond them.
The idea hasn't changed, this is not about how much you can make, but about how much you can make holding versus other methods. And the idea that you could still make a lot of money from holding is still true. Yes you may not make 10000x profit from holding bitcoin anymore that is true, $1 invested into bitcoin will not become 800k ever again, that is true, but the fact that you could make more money this way than any other method is still true.
All you have to do is buy bitcoin as much as you can afford without hurting your finances, will return with the most profit you could make in the finance world almost all the time. This is why you may not make that much, but you will make the most out of your investment with holding bitcoin. A 20x return is not out of question if you wait enough, 1 million dollars per bitcoin could happen in the future, not today, not tomorrow but maybe 10 years later?
