Despite recent rumors that Twitter will soon implement restrictions on all ads related to cryptocurrencies and ICO, the company’s CEO has a totally opposite view on Bitcoin. In his recent post, Jack Dorsey said: “Bitcoin will overtake the dollar in importance as it becomes the single global currency of the internet within a decade”. Dorsey also admits that currently, Bitcoin does not fulfill his prerequisites for transactions, being too slow and expensive. However, he believes that as more people will use, it will become better and eventually by the year 2028 BTC will be the only currency online.
