Why do people keep investing in theses new alt-coins, do they really think that in one years time, that they will ALL still be around? Or is nobody really investing in them but simply using them as a bridge to make bitcoins and litecoins.
I just mine altcoins that seem interessting till i have 10-100 (depends on difficulty etc.).
In this way it won't really cost me anything and i still have the profit if the coin might shoot up in value somewhere this year.
Besides that it's just fun.
