I'm buying some LTC lately. No nonsense, no tricks, no b/s coin. Very well known, liquid (always been in the top 10 by volume), much mined and much undervalued (now still close to an all time bottom in price).
It solved the spam attacks very logically years ago.
It seems to me what BTC should have been.
BTC is the gold, LTC the silver. When gold fails go to silver
