The 2013 crash was more brutal. Remember that there was only MtGox back then having most of the liquidity in Bitcoin. If there was a tiem to think Bitcoin was going to die, then that was the MtGox apocalypse.
The fact that Bitcoin survived that made me realize how delusional people that think Bitcoin will ever die are. Now we have tons of different sources of liquidity with different exchanges. The fatal 2013 scenario cannot ever be repeated again. The current crash is just a healthy correction after the market went apeshit. At a slower pace, and with much better fundamentals. The bottoms keep being higher than the previous bubble's peaks which is all that matters .This is called progress. Long term we've never stopped going up. Of course short sighted noobs may argue otherwise.
Mt Gox was well on its way to being replaced by the time it died. BitStamp was well established as was coinbase. Bitfinex had started up along with others. we weren't as reliant on Gox as you suggest in 2014.
True, Bitstamp was up and coming already and actually surpassed MtGox in terms of volume at some point (that was when problems started stacking up and rumors of bankruptcy and shady behaviour were already being brought up), however, the amount of bitcoins stored in MtGox was as far as im concerned way higher than the rest of exchanges combined.
So it was like an huge ticking time bomb and by bomb I mean a proper 850,000 BTC nuke. If you look at the biggest bitcoin addresses nowadays, I don't think there isn't any exchange that has that many coins even if you combined a couple of the biggest addresses. Now the risk is way more diversified and we can no longer go back to the MtGox bad fundamentals so everything after MtGox feels like a joke and mindless FUD.
