what do you mean not for you ? you already sold your coins right after 2017 bull run ? thats really an emotional exepriencing knowing that you have lost and seeing everyone earning during this period  but why not try again instead of blaming the coins or your self . like what one of the philosopher said , in order to be succesul , one must not blame but instead we must learn to accept things and accept that if was your own mistake not by the coin or by others predictions.
