Just for a better and more accurate headline, this is what he actually said: "My plan would be to start very, very small, perhaps 1% of issued T-bills would be backed by hard currency, by gold, silver platinum or bitcoin".
Great news nonetheless, but it's probably getting overblown.
Any news on Bitcoin always gets hype and if a presidential candidate is constantly discussing Bitcoin then it will get overblown. As of now, he is just a candidate, who wants to win the election, and therefore such statements are coming out of his mind. In all cases, if he wins, I doubt he will ever implement what he planned and what he has spoken in the past about Bitcoin.
I believe he’s a smart candidate actually because he’s using bitcoin for his own advantage, but at the end of the day, if ever he wins, I don’t think he’ll still think about his promise but eventually forget everything about bitcoin. Just like any election candidate, he’ll do everything to convince people but once he’s in power, it’s still all about fiat and fulfilling his greed for his own desires.
