I am sure that Ethereum should be bought, despite the fact that its cost has fallen greatly. It doesn't really mean anything. The project itself is currently recording an increase in Ethereum adoption in developing countries. The decrease in capitalization is not a sentence. Don't panic.
Such reductions ARE a destiny. Because when you had bought at the price of $900, and then it fell to $90 it's bad! You may calm them down, but such prices really strike people. And I guess, we'll fall below.
