Bitcoin is just used for some reasons to people to make their self rich with this. And somehow a lot of people doesn't even care what could it do in the future.
That's not true. None would ever think that will get rich this Bitcoin. Of course, there are many people that they think of getting rich by owning BTC but this is just a small portion. If these people haven't studied about it in the first place and came for the technology itself then they just harm the cryptocurrency community by being part of it and bringing toxicity.
Unfortunately, he is right though. Most people come into the crypto space to become an instant millionaire. I've seen enough to know this much is 100% true. I myself came into this space because of a youtube video that said I'm gonna be a millionaire. Almost 2 years later and I'm still not a millionaire but I'm here for good.
