I think the two coins are good coins. and many people who use the coin, used for investing or trading day-to-day. I think it all depends on each person and depends on the initial capital you want to invest. if the capital is only a little, I would advise to buy ethereum. but if your capital is enough, better buy both. and I prefer to trade daily rather than invest long-term. by having a different type of coin, we can look for profit by seeing the development of coin with one another. and when one coin is at a favorable point if it is sold, then we can sell it. and wait for the other coin, if we think it is not worth the sale. with such a strategy, maybe we can earn an income.
