I believe the next wave of the bull run is about to erupt as CEO of the biggest asset management firm BlackRock Larry Fink said bitcoin can evolve into global asset. There are more big guys from Wall street getting involved in bitcoin too. We won't possibly see any serious corrective retracement anymore.
https://www.coindesk.com/blackrock-ceo-bitcoin-global-assetBitcoin is already a global asset,it was a global asset right from the beginning,there's no need to evolve into such asset.Bitcoin was never a national/local asset.

Can you mention a few "big guys from Wall Street",who are currently getting involved in Bitcoin?
I don't know about any Wall Street "big sharks" buying BTC right now.Maybe they are keeping their buying process confidential.
