Many people started writing to me about problems with paying for this service, about PayPal not working, etc.

Here I want to discuss this in more detail and speculate a little about the solution to the problem.

First frequently asked question:
"Can I use other payment services to support you?"
Unfortunately, this is almost impossible. At the moment I live in Russia, because of the sanctions that were imposed on this country since the beginning of 2022, all connections with foreign banks were effectively "killed". There are not many transparent and safe ways to transfer currency from one to another. Well, or I did not look hard enough, who knows?

Second frequently asked question:

"Can you use PayPal and other similar services?"

Unfortunately, no, PayPal and others have also suspended their operations in Russia. Of the options that in THEORY could work, there are still some that are quite absurd and inconvenient for those who will support me... But I will still list what I managed to find.
FunPay - as I understand it, this service manages to work adequately with both rubles and other currencies, and it also has a fairly good reputation, but since it is tied to the sale of games and similar things, I will have to think about how to sell myself there.

HopoLink - another service similar to Boosty (if I'm not mistaken, it is indeed somehow connected with Boosty, perhaps they both have the same authors) I recently heard that, unlike Boosty, it can work with foreign currency, but lately it seems to have the same problems.
Below I will list options that might work, but it sounds really crazy, so it is unlikely to be used.

Crypt

Dubious purchases of virtual cards (with huge commissions reaching up to 20%) and a high chance of being deceived

Well and interaction with people who can accept foreign currency and transfer it to me in return for rubles is essentially the same as buying virtual cards...

To sum up the above, there are very few options left. From what I can advise to those who are having trouble with payments. 

Try asking those who are doing well with payments on Boosty in the comments or pm, maybe they will help you. Try other possible payment methods. Another option is to use virtual cards or intermediaries, but this all entails a commission and associated risks. Therefore, I want to warn you, no matter what payment method you choose, be careful and do not trust any dubious dudes. 
Once again I would like to apologize for all the inconvenience, unfortunately there is little I can do now.
P.S. - For those who really want to pay with crypto, my answer is negative, I have never used it and do not know how. Maybe someday...
