I'm consistently putting small amounts into ETH and LTC as a kind of emergency fund that likes to grow. When, exactly, do you guys think that the recent surge in BTC will result in a "catch up" surge in ETH and LTC?
A simple way to trade if you don't like putting money in Tether or other stablecoins, and don't have time to follow the intricacies of each coin's development, is just move money back and forth between BTC and alts depending on relative strength. So at the start of a bullrun this means move to BTC, and then when BTC growth starts to slow, then move to alts... and then back to BTC for relative safety if the market starts to turn slightly bearish.
