Several Bitcoin (CRYPTO: BTC) mining stocks including Marathon Digital Holdings Inc , Riot Platforms Inc  and CleanSpark Inc are moving higher Wednesday amid a rebound in the price of Bitcoin. Here’s a look at what's going on.

What To Know: Bitcoin briefly hit new all-time highs when it crossed the $69,000 level on Tuesday before retreating all the way back to around the $61,000 level. Bitcoin is bouncing back again on Wednesday.

Most have attributed the recent rally to a surge in demand following the approval of spot Bitcoin ETFs in January. Many crypto market participants are also looking ahead to April's halving event as the next potential catalyst.

Pomp Investments' Anthony Pompliano on Tuesday noted that the ETF approvals have pushed demand for bitcoin well above the available supply, which is creating massive inflows. With the halving coming next month, it's hard not to be bullish on bitcoin right now, Pompliano said.

The longtime bitcoin bull also told CNBC that the price of bitcoin has doubled in 18 days or less three of the previous four times bitcoin has eclipsed all-time highs.
