I personally doubt BTC will go much beyond USD 100k,- but that's only because I honestly can not fathom BTC reaching the estimated market cap of all the gold in the world. Then again I love being positively surprised.
"corrections" are never big or epic or anything, they are always logical and properly sized.
Mt. Gox.
Will it happen again?
Mt. Gox had 75% of trading volume I think.
So if it happens again it cant be an exchange. Has to be
something else which is centralized. The other idea would be the failure of USDT, but I think perhaps dependence on it has waned since earlier in the year? The other idea would be a massive crackdown on ICOs, but I doubt this will come all at once.
I'd also say that Bitcoin is safe from exchange failure by now. The exchange ecosystem has become incredibly diversified. Besides, people withdrawing their coins in time for the BCH hardfork pretty much prove that all major exchanges are liquid and not running fractional.
ICO crackdowns affect ETH more than they affect BTC. There might be a dip, but I doubt it will have a serious impact on BTC valuations.
In my opinion USDT is crypto's achilles' heel right now. While its market cap is comparably small, it still has quite respectable trading volume and is permeating pretty much every part of the market.
