Yeah...I go back and forth as to which has the most potential between LTC, BTC, and ETH.
I feel that BTC will be the store of value and really hit the gold market. LTC makes sense for the micropayments since it is ultra fast compared to BTC. ETH has the smart contracts but Lee mentioned implementing them into his system at some point also.
ETH seems to have attracted the major corps to build upon their network.
RE: LTC at ATH...pop $70?
