You are right, Ethereum is the ultimate vaporware.
NEM reminds me of Litecoin, a copycat, same code, same looks, just changed some parameters and the sales pitch. Sorry, not going to cut it.
SuperNet is not even a cryptocurrency, it's a bunch of assets that promise to deliver services and a share in some altcoins, also known as a fund where you trust all your money to certain people...
Mind boggling that someone chooses to invest in vaporware, copycats and funds, and choses not to invest in Bitcoin and NXT.
