I strongly agree with you to choose ETH as a very good investment list and keep it in the next few years so that you don't give up on the way, I don't recommend LTC as an investment list because I see that LTC won't improve like ETH because there are more market demand held by ETH when prices rise, it will be a very profitable opportunity, the most sought after seeing Bitcoin as the main thing, the current conditions are very good when the market is always trying to pump quickly, maybe it needs better adaptation to plunge into some long time.
