Some bubbles will burst for sure, others will stay and become even bigger, and maybe they won't burst at all. Bitcoin is biggest bubble and wont burst if there is constant demand for it. This fact won't change anything, we could soon see 2k$ BTC we all know this.
Bitcoin is losing almost 1% per day of the total market cap, I still holding some but seriously considering switching more to alts before the flippening really gets crazy.
