Seeing the historical performance of the crypto market, there have been multiple cases of altcoins that having reached a significant value, have fallen in such a way that practically their current value is zero. Therefore it is perfectly possible that virtually any cryptocurrency could lose all its value in the long term, and even more if we take into account that sooner or later the current cryptocurrencies will become obsolete in the face of the inevitable technological advances of the cryptos of the future. So I believe that the current critical conditions of the market have taught us that we should be smart enough to buy and sell at the right time, without blindly committing ourselves to the idea of "hodl".
