ETH is one of the best currencies for long-term investment. We are all aware of the growth of Bitcoin over the years. My reason for recommending eth currency for investment is that there were many currencies that reached the top 5 in terms of rankings for a while, but went down in the rankings after a while. Litecoin, for example, used to be in the top 5 but is no longer.
eth cryptocurrency has been in second place for a long time, and despite some efforts to reduce its marketcap value, it is still in second place.
