It is very difficult to find good websites about cryptocurrency market news in Russian, but you have them and it's cool. I would like to know if I buy some expert material, how long can I use it?
An interesting question, really. I have not seen such parameters on the site, but I think that access will probably be active for a month or a few weeks. Although I do not exclude that buying an article once, you will have constant access to it. We'll see what concept the developers will offer.
