What is driving this pump?

So I’m sure everyone here (alright MOST people here) are sat watching this huge rise from $16k with a mix of euphoria and disbelief, I know I certainly am. After months of flatlining and crabbing we have seen what appears to be a release of a tightly pulled elastic band and an almighty move north for Bitcoin and subsequently all crypto tokens – anyone got any view on what has caused or is causing this? I’m assuming that much of this upward momentum is fuelled by some gigantic short positions being unwound but even with that surely there must be some concerted efforts by big players to buy heavily?

What has changed in the crypto landscape that has seemingly put all of the bankruptcies and shenanigans and nonsense of the past 6-12 months to the side and caused some huge buying to begin?

And lastly: is this the end of the Bear market and have we seen true bottom for this cycle of the Market at circa $15.5k ????????????
