Ethereum is good choice for long term. Ethereum is top 2 coin in marketcap. it is well-known crypto
furthermore, early next year would be launching Ethereum 2.0. many people have high hope on that news
So, I think it is good decision if you wanna hold it.
Everyone has a different opinion about the Ethereum because from 2018 the price of ETH is speculating hugely and in the coming days the price of ETH will surely increase due to huge development will release in the coming days, till now, we have seen such huge trend in the market for ETH. It is not managing to improve its price, but staying in the same position.
