Just think of it this way. The big fish want those impatient weak hands to lose their faith in crypto and sell to them at these super cheap prices. Then sometime in the future when crypto is booming again & your enthusiasm has returned, they will sell these same coins back to you for a hugely inflated price

If nothing has fundamentally changed within the crypto market (regulations, alternative competing technology etc) then there is no reason to lose faith, so hold & wait.
