According to Michaël van de Poppe, there has been a significant shift in sentiment towards Bitcoin over the past year. Last Christmas, when Bitcoin was at $40,000, it was perceived as a declining asset. However, this Christmas, with Bitcoin reaching $100,000, interest has surged with people eager to learn about investing in Bitcoin. There is also speculation about Donald Trump potentially holding Bitcoin on his balance sheet, highlighting the changing perceptions and growing mainstream acceptance of Bitcoin.
