At least re-iterate your subject topic to "the capital of the world of cryptocurrencies" so that it will be just on crypto not digital currency as a whole .
Well, cryptocurrencies are becoming a trend already and it started when it went up so much in the past months and in 2020. Its true that the Mayor of Miami has been vocal with his support towards Bitcoin but it doesn't mean that it is already the capital. ATM's doesn't matter much at least for me because we've already seen many ATM's globally but there is only a few percent of the people around the world who either knew or using Bitcoin.
