I am not sure why are you restricting yourself while choosing the coins with only two in the bucket. You can expand your wings and chance of getting profited with ETH, XRP and other coins out there. I mean there is no point ins ticking to LTC only. There is no question about the bitcoin but it is really very high and with whatever small investment you may make it would be very small and with the little change in the prices of bitcoin it won't rise much. To make quick and trusted trades you should start looking into portfolio of ETH, XRP and LTC if you like it that much. These coins can make you profited in the future if you hold for long terms.
