Since you didn't post this on a local board, you might want to consider creating an English version as well ^{[users shouldn't rely on translations made by Google due to its inaccuracies]}.

Based on point 11.4 of your TOS, it appears that you'll ask for KYC stuff in certain cases.

BTW, in point 5.1, there was a mention of refunds on receiving different amounts that exceed by more than 10%... I didn't see any fields for refunds, so am I correct in assuming that this part is automated?
