If Bitcoin was a scam, you will not see people proceed into investing in Bitcoin like the way lots of people are investing in it today. Bitcoin has made some people to be extremely rich, including some traders who have become rich because they are trading Bitcoin on centralized exchange. There's no way to allegedly prove that Bitcoin is a scam, only the people that don't have legit knowledge about Bitcoin will think that it is a scam.
It's not BTC that makes people rich, friends, BTC is an investment tool which, if done correctly, will bring profits and the time period is also short. This is one thing that is different from other ordinary investments.
If it says BTC it is a scam. Of course, my opinion is the same as what you expressed above, no, that's far from my current thinking.
