It's 12 years since Satoshi released Bitcoin whitepaper and since then, the numbers of believers have been increasing. Which turns out that it's good.
Cryptocurrency is freedom, and who doesn't?
Decentralization isn't scam. It's open source. It's the best gift. Only a person without proper understanding will think it's a scam.
And that is indirectly saying that the OP has no proper understanding.

If you will look at his post history, he has some bitterness to bitcoin or crypto but wonder why he is still here wasting his time, if he doesn't believe in bitcoin. Anyway, we don't have to assume that bitcoin is scam because it is not. Plain and simple.
I see, he is is just casting doubt to the people who are not familliar with it and maybe he is someone who doesn't really like how bitcoin dominated the entire crypto market. No matter how you guys work to dirty the names of Bitcoin, it won't really do anything to its current value. Just live your life to the foolest.
