Sorry for my english, I'm french:
just a question, an exchange platform will she propose yacoins, if yes when ?
There will be infinite new copy-cats to BitCoin and LiteCoin, but only some will end up on the exchanges, most will never amount to anything and die.
So every time you jump onto a new coin trying to get rich early, you could potentially be wasting your time. And the time spent on "X"coin could have been spent on a working coin.
