Matthew Sigel, head of Digital Assets Research at asset manager VanEck, expressed great optimism about Bitcoin's future price performance in an interview.

In a interview with CNBC on Monday, Sigel described the situation for Bitcoin as "very bullish." He attributed the recent surge in the crypto markets in part to the increasing likelihood of an election victory for Donald Trump, whose odds on the crypto betting platform Polymarket currently around 66 percent lie.

Sigel compares the current situation to that before the 2016 U.S. presidential election. Then, too, the BTC price lagged behind other asset classes, but after a long period of low volatility, Bitcoin staged a strong rally after Trump's victory.

A few months ago, Sigel attracted attention with a bold prediction: by 2050, BTC could reach a value of $3 million. He now explains that this would equate to an average annual growth rate of 16 percent over the next two decades, which on reflection does not seem extreme.

VanEck is convinced that Bitcoin will become a global reserve asset. As "digital gold," it should be held by central banks at a weight of two percent. In addition, the company also sees BTC as a means of payment in global trade.

Sigel did not make any specific short-term predictions. Asked about Ark Invest CEO Cathie Wood's prediction that Bitcoin will reach $500,000 by 2026, he replied, "I don't think about it much."

He describes the progress of BTC adoption in a down-to-earth way, "New buyers are coming in every day. The older ones who hate Bitcoin are dying out."

Sigel also highlighted the growing interest in Bitcoin from BRICS countries such as Argentina, the United Arab Emirates and Ethiopia, which have already started mining BTC with state funds.
