Hmmm, if I'm in your shoes and made millions of USD as you have claim, I will just sit back and relax and will not post in this community, LOL, not unless you are promoting something here in the community.

Bitcoin has been compare to many tulip bubble in the past, but as you can see those tulip bubble are already dead while Bitcoin is still going strong in the next 10 years or so. That's why I don't consider Bitcoin as a ponzi scheme or a scam, we continue to make money out of it and we can call it a bust when the price literally goes to 0 but I don't think it will happen. And even if the last bitcoin is mined (21 million)? It will survived, IMHO.
