I don't understand why people ever thought that a crypto currency that is centralized in some way or form would be a good idea when the whole decentralization thing is one of the biggest pros of bitcoin.

Just as this other coin, I can't remember the name, apparently has no real cap to it's total amount, yet people were buying into it even though having said cap is what made bitcoin great.

I'm no genius when it comes to crypto and finances, but these did not seem all that reasonable to me.
