And you are wrong as well.
Bitcoin is not for speculation. It is also not a "meme investment".
Bitcoin is a currency and a sophisticated payment system that is working globally and 24/7 without ever shutting down. That gives it the value that goes up and down then it attracts investors who see it only as an investment.
You might think that, but 99% of Bitcoin holders just see it as an investment instrument.
As a payment system, Bitcoin is terrible, costing up to $30 per transaction and taking up to 30 minutes. That's insane compared to an ordinary credit card transaction. That's why almost nobody uses it that way.
And Bitcoin isn't even private, and using Bitcoin for a payment is much more dangerous than using a credit card since your transaction is publicly viewable forever.
So Bitcoin does not have any unique
practical use, thus it's only useful (and very useful at that) as an investment instrument. People buy "Bitcoin" because they thing "Bitcoin" will go up in value--and for almost no other reason.
