In any interview with Fox Business, Mayor of Miami, Francis Suarez, revealed his thinking in terms of attracting tech businesses, and specifically bitcoin and crypto businesses, to Miami:

We want to be one of the most crypto-forward and technological cities in the country. So we're looking at … creating a regulatory framework that makes us the easiest place in the United States to do business if you're doing it in cryptocurrencies.

Mayor Suarez also specifically noted the possibility of putting Bitcoin on the City of Miami's balance sheet, plus some of the reasons why it can be considered an attractive investment:

We're looking at the possibility of diversifying our investment portfolio and holding a percent of our investments in bitcoin.
The fact that it is limited, the fact that other governments use currencies to do a variety of things that have nothing to do necessarily with the exchange of goods, but to implement public policy, I think has made bitcoin a very attractive investment for many people.
