I hope this will not happen in the very near future we are still in recovering period and another decline or bear market that may occur can totally crash the whole altcoins I saw last year some of my prospect altcoins that I believe can give me huge profit for holding but opposite happens it down to almost -95% up to now time will tell if they can recover or not.
It took a long time for Altcoin to get back on its feet. In a bloody situation like this, the miners must really be able to rack their brains and find new ideas, so that the coins they develop can continue to survive. If not, we can be sure their coins will disappear in circulation...
