The digital currency is currently still near all-time highs, but bullish calls remain for the asset. One investor thinks it could almost double to $4,000 by the end of 2017.

Bitcoin hit an all-time high in late May, reaching to $2791.70 according to CoinDesk data, recording a 180 percent rally year-to-date. There was a subsequent price correction towards $2,100 but bitcoin currently stands around $2,468.56. The market cap for bitcoin has swelled to more than $40 billion.

The bitcoin rally has been fueled by several causes:

Daniel Masters is the chairman of XBT Provider, which offers a "bitcoin tracker" that can be traded and exchanged on the Nasdaq exchange in Stockholm. He expects Bitcoin to reach $4,000 by the end of the year.

"Bitcoin is emerging as the transactional layer of the internet, as programmable money and as digital gold. That's the big picture," he told CNBC's Squawk Box on Thursday.

Masters says the trend for high volatility in bitcoin is being diminished due to bitcoin's proliferation, with more products and exchanges set up, as well as the development of a short side of the market. He thinks the next catalysts for bitcoin price growth will come from greater volume.

"What we've seen at XBT Provider is an increase in coverage and an increase in penetration into both the retail and institutional market. We're now being covered on Nasdaq OMX by 27 different broker dealers, and that is a stark increase from what we saw a year or two ago," he said.
