By reducing the price of altcoins, there is an opportunity to attack 51%. As a solution to the problem, I see the creation of a pool of coins and a miner who will switch(temporarily) mining powers to coins in which the possibility of an attack of 51% has occurred(one of the pools received 51% hashrate). Developers and miners will benefit from maintaining and mine on such pools, as this makes the coins entering the pool more crack-free.
