We should always be ready to accept losses when investing because it is inevitable. But you will lose everything only if you are investing in shitcoins, if you invest in top coins and don't sell in panic you will never lose. Try to hold the top coins and don't forget that bullrun will come back, panic and sell while price drop can't solve the problem, you should be confident with what you chose earlier.
This used to be a very promising project and what ICP is doing now is so poor and forgettable that it bears no comparison. I have a feeling ICP is the next EOS version.
Bitcoin is below $20k again today, and the two coins you mentioned are likely to fall further due to this drop.
