I also prefer crypto payout methods for personal sentimental or ideological reasons. Moreover, many of my foreign and US contractors had difficulties with bank payments, severe local corruption, and bank account processing. These problems are usually happening because they are from traditionally unbanked social classes, they are not legally resident in their resident country, or they are in developing nations where good quality banking services are not aligned with their social class. But I would not deny that some could be attempting to avoid paying taxes or other such traditional obligations.
More than half of the international contractors tried cryptocurrency options. Many of them cashed out pretty instantly and I've heard they had no big problems doing it. Several kept their cryptos for years and they have made ridiculous profits now, even enough to retire. But I've also heard that a few timed the markets unfortunately or made bad side investments and lost a lot of the money they earned.
