well I'm mining altcoins, trading some for BTC, keeping some as lottery tickets. There are too many of them though, difficult to tell which ones will prevail or even survive the upcoming years.
If we only knew...
I actually do have a couple of coins I consider legit and with good perspective, but unfortunately, or fortunately, I'm better off by mining more profitable coins and trading them for the ones I really want, than to mine what I support directly. By not doing profitability mining I am being "robbed" by others who do, and there's to many of them.
