Paypal and Payoneer no longer work in my country, so I can't get money from Ko-fi, Gumroad, Buymeacoffe and ComicAd (the ad banners here).
The only tip jar I have left is Boosty. It accepts Paypal, all cards, any currency, then it converts it into rubles and sends to me. Boosty works the same way as Patreon + accepts one-time donations like Ko-fi and allows selling ebooks.
