I don't think so. Crypto taxation in those 5 countries has been taking place for some time now, and there have been no reports whatsoever that are related to the pump and dump in the price of crypto since then. For tax purposes, cryptos have not treated by those countries as currency like the US dollar, instead, they're treated as property like real estate or gold, or a capital asset like stocks, bonds, and other investment properties, and thus it is subject to tax.
