Eth is good for long-term investment, but number 1 is still in bitcoin. But the opinions of the holders of one another are certainly different.
If indeed ETh has provided many benefits, it is only natural that you make no. 1 long-term investment.
No doubt ETH is one of best coin which can make you earn profit and it is best choice but not the only one or number one because number one is bitcoin for sure, we are having number one crypto and that is only bitcoin because bitcoin is king currency and it is mother of all other crypto coins, so being agree I would say number one is only BTC.
