I suggest investing both of these coins because they have a high volume capacity, eth and BTC have a very high value for future investments
I can't be sure if in the future ethereum and bitcoin will still have high value. because now the market movement of bitcoin and ethereum looks up and down. it became natural, but I myself limited the time for my investment. because I will not save assets in the really long term.
Regarding that matter, I am very confident that the future of the two coins between bitcoin and ethereum need not be doubted because it might have a high value even though until now there has been no significant development of the two coins but we must remain optimistic
optimism is the main thing that keeps people in the market, and now when growth began. Its necessary to have both bitcoin and air in your portfolio, because they will not grow in the same jerky way, and in exchange they will sell and buy while looking at the course of the aether-bitcoin
