What spurs up most people is the greed to make their own riches out of the ponzy scam crypto projects that they launch into this space. When it comes to marketing there are equally marketing and promotional platforms that equally don't care about their reputation but the money they make hence launch any scam project into the space. The only cryptocurrency to ever invest in is Bitcoin.
I generally support your point of view however it's important to be reasonably critical of where Bitcoin is heading right now. I agree that at the start this was the only true crypto, but you have to DYOR and understand that it is now governed by a team of developers that don't really do much to make it more rich in usability. Maybe that's for the better, which is arguably true. But don't you think that at least Ethereum is worth something just because of smart contracts? Sure, the numerous erc20 shitcoins issued on Ethereum network are worth nothing, except, maybe, for things like BAT. But Ethereum was a game changer in some way. Still is. What do you think about it?
