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
