Bitcoin 2.0? Why? Bitcoin 1.0 is enough.
Actually we don't even have Bitcoin 1.0. These coins claiming to be 'Bitcoin 2.0' are just using that as a marketing scheme to promote themselves. They offer nothing of real value, nor are they ever going to take a good market share.
I guess I don't have anything against crowdfunding Bitcoin related projects, however doing so for coins is not my preference. We have enough coins as it is, and if someone was actually trying to make something better they would not ask for money. Let me remind you that satoshi did not ask for funds and whatnot.
