You are 100% incorrect. I worked at Circle which had the second-largest OTC desk while I was there, and $3 million in BTC even back then was trivial. The markets now are ~25x more liquid than they were a few years ago. I don't think you know even the smallest thing about this industry because your comment is so entirely mistaken it reveals you are clueless. Converting from BTC to rubles is a different matter but BTC / fiat trades of major currencies is very easy for USD and I can't imagine rubles are difficult.
