if I choose Ethereum, because I believe that the price of Ethereum will increase very high, therefore I invest in Ethereum and hold it for the long term, because I believe that the king of altcoin (Ethereum) will continue to increase in price and always create a new ATH price, so from that I believe to investing in Ethereum for the long term.
