this is in russian as you said. but I used google translator tool to translate. I don't trust these type of sites honeslty. and I can't see any bitcoin accepted tag too. so no recommended from my side.
it is not opening page , access is not there , not sure may be not active, try to search on google or some more information you may get. always best is not invest more money on unknown sites , best is to invest little and also look for legit kind of sites , some sites does not promise as expected.
why should someone invest little money to unkown and scamming sites? scammers don't deserve a single penny and innocent people don't deserve to loose a single penny.
