The value of bitcoin surpassed $50,000 on Monday for the first time in more than two years. Analysts believe that the rate cut expected from the Federal Reserve this year, plus the halving that will generate a shortage of the asset are creating a new context for the resurgence of bitcoin.

Nine bitcoin funds began trading in the US on January 11 and have so far attracted more than $9 billion in investments. Two of the offerings, from BlackRock and Fidelity Investments, appear as the most successful ETFs ever launched based on assets obtained after one month on the market.
