That's a risk that I'm sure the folks at MtGox have taken into consideration, and apparently they've deemed the juice worthy of the squeeze.
I can only imagine how many people will end up in the hospital due to massive hand to face trauma when that happens...
If you guys have so much shit to say about a company that honestly didn't really do anything wrong and has been adjusting to its environment pretty well and also held itself accountable the one time it got hacked. I'm not a fanboi, I don't even have an account there. I just hear people bitch bitch and bitch for not many reasons honestly.
Uhhh, Coinotron says it has protection too...but that doesn't stop attackers. Gox has been down plenty enough too, so whatever claims of protection are probably not working/going to work. Especially once all the DDoSers see that they can earn more attacking MtGox for LTC than the LTC Pools.
But hey, you aren't the first pessimist in this world.
Skepticism is quite healthy, especially in this market.
