Of those 13,000 requests for information, at least 732 were sent from Spanish authorities, according to Coinbase, which also revealed that other Spanish-speaking countries have asked them for information about their customers. These are Costa Rica and Colombia, which sent 6 and 3 petitions this year, respectively.

The U.S. was the country that requested the most customer information from Coinbase, with 5,140 requests sent to the exchange this year. It is followed by Germany, which sent 1,906 requests, and the United Kingdom, which sent 1,401 requests to the San Francisco, California-based company.

Other nations around the world also asked Coinbase for information. This is the case in Australia, Portugal, Armenia, Italy, Canada and the Netherlands, according to the bitcoin exchange's transparency report.

Something that Coinbase highlights is that most of the requests for information they received this year came from government law enforcement agencies, such as tax or government offices, as well as regulatory superintendencies.

The exchange also highlights that 95.6% of the requests submitted were related to criminal allegations. And only 4.4% had to do with civil or administrative matters.
