Both of the coin that you chooses are good to invest with especially these are the top 2 rank cryptos in the market and if you want to hodl it for a long term basis they are the right coin for you. However if you are just here for a short term investment better to do your research in NFT tokens because that is the trend as of this year and I don't think that ETHER and Bitcoin is beneficial for you in just a short term run.
