People invest...ahummm...gamble with altcoins just because they are greedy and constantly looking for something that changes its price significantly every day. And exactly that is the case with altcoins. It has nothing to do with the fundamentals of Bitcoin. People are addicted to the high fluctuations that altcoins give them. This has nothing to do with investing either. It's ordinary gambling that people do.
Finally someone that is talking real stuff. In most cases that people experience slow confirmations, it is because it's their fault. People not inculding sufficient fees with their transactions are the one to be blamed here. But still, it's Bitcoin that is slow, or boring, or whatever. Ignorance....
