A Miami Beach, in Florida, si stanno raccogliendo migliaia di appassionati di cripto-valuta per la conferenza Bitcoin 2022. Decine di aziende stanno utilizzando questa conferenza come piattaforma per presentare idee agli investitori o condividere annunci per il mondo cripto.

Le Banche centrali stanno riflettendo su come affrontare questa sfida globale, perché la tecnologia Bitcoin è un sistema di pagamento valutario internazionale, ideato nel 2009, che non ha bisogno del controllo centralizzato da parte degli enti nazionali o internazionali. Il valore del Bitcoin dipende solo dal bilanciamento tra domanda ed offerta.

L’unico inconveniente è che, utilizzando un database distribuito tra i nodi della rete che tengono traccia delle transazioni in formato criptato, richiede enormi potenze di calcolo (AP Photo/Marta Lavandier)
