This is an article from pravda.ru, as I understand from their description is a tabloid and one of the lowest of the low, but it is still owned by people in the government so I guess they won't publish something that might hurt the reputation of their country without a bit of truth somewhere in this.

After the announcement by the West of new anti-Russian sanctions, the life of Russians has changed significantly, changes have affected almost all spheres of life, including sex services.
Russian prostitutes began to take cryptocurrency from clients
Recently, prices for intimate services have shocked even regular customers. A date with a domestic nymph will now cost 40 thousand rubles per hour (!) As the source of the publication explained, this is due to the fact that, along with Western brands, foreign lovers of such leisure have also left Russia, and "models" have left the country behind them. Since the demand has not gone away, we had to increase the cost.
Another significant change in the underground market is associated with the volatility of the ruble. The exchange rate of the Russian currency changes so often that many escorts have decided to switch to bitcoin.
"The world is now so restless that it is safer to keep your hard-earned money in a crypto wallet!" - says the interviewed prostitute.
Now we had dancers getting tips with QR tattoos, we had escorts occasionally taking crypto payments, but now we have (if we believe this) an entire industry that is moving to ditch the ruble for cryptos as probably dollars are now even harder to get, especially with a ban on foreign currency purchase. Tossing aside the fact that probably this still happens at a small scale and most of the escorts there probably are not accustomed to bitcoin nor do they have the means of exchanging those for goods and pay for stuff without rising eyebrows I can see a bit of hope this thing might be catching a bit of momentum.
The country has blocked people from seeking a safe haven in foreign currencies, the trust in their own is down the drain, but on top of that if you want to get stuff that is no longer available for import there you need to seek it on the black market, and what I've learned in 20 years of communism is that nobody there will accept anything but foreign currency, in my case, it was dollars or marks or get the fuck out!
So, do you see this trend going on and become nothing relevant or not, and at the same time do you think the authorities will try and squash this before it gets any traction and will of course harm their efforts of currency control even more?
