I dont believe that altcoins will turn to dust when lightening comes. Of course i support bitcoin, too. But some altcoins seems very reliable to me and i dont think they will just disappear. Eth and neo are good to hodl.
There is more than 1950 different coin and token in market and i think not many will survive. Altcoin will survive if they have good product and strong community. Ethereum and NEO is good coin and i am already hold that coin.
