I doubt the UK and other European countries will do the same as the UAE, a country that has had high taxes on many things from the start will do the same on other things including crypto transactions, only countries that have never implemented taxes or low are also likely to exempt crypto from taxes or only apply low taxes on crypto transactions.

The UAE has quite low taxes, some are even tax-free, so it's no surprise that they also do this for crypto, crypto lovers in this country are certainly happy with their government's decision.
