If the coins were stolen will be a mega dump, I hope not, believe in this coin
Hackers are not stupid. They want maximum profit so IF the coins were stolen they will not do a mega dump, but sell off little by little so as to not spook the market. The Gox stolen Bitcoins were not mega dumped because I am sure the BTC market would have noticed a dump of a few hundred thousands BTC. They are probably being sold off little by little.
In general there would be a bigger risk of a dev of some coin dumping premine than a hacker dumping a stolen wallet. A stolen wallet would mean a longer term income for the hacker.
Again this is all just speculation.
I would like to make it as you write, I unfortunately could not stand and sold for 2,4k, maybe because I bought for 1k 100% certain profit is me enough.
