Yeah learning the hard ain't fun but it always helps me to not make the same 'mistake' again. Nice that you've gotten some ETH at 40 bucks! Holding on the the currencies is in my opinion the best strategy for now. And I just reconsider my holding strategy everytime there ar new important developments. Overall holding on to the coins you really believe in will result in the highest profit I think, plus you don't have to put in the time for trading:)
