But it looks like a different type of bubble this time.
Last time mtgox had vastly bigger rates than all other exchanges and faked/bot created (mtgox bot!) trading volume.
So the bubble was due to market and trading manipulation.
This time at least the price is surging across all relevant exchanges:
I don't know what that means for bubbles and when they are expected to burst. The only thing I realize is that Bitcoin transactions did become much more expensive over the last week
If the BTC price rises faster than the Bitcoin network hash rate, Bitcoin might be able to survive the next coinbase reward halving (in less than 38 weeks; even sooner if the hash rate arms race gets fueled again) with little or no harm.
Woulda, coulda, if, in case of, etc.
