If you have ability to hold some coin I believe that ETH will be more profitable from other. I know many alt coins are very low price now. But for me eth is better to hold a little bit. I believe you will never loss.
ETH isn't a bad choice if you want to hold and invest in cryptocurrencies. But don't say that "YOU'LL NEVER LOSE." What if your friend bought ETH at $300 and it became $100 tomorrow? What will be your alibi to your friend since you guaranteed that they'll never lose?
