Russian Sergey Mayzus is a notorious entrepreneur in high-risk payment and online trading. He founded the now CySEC-regulated broker InstaForex in Russia in 2007, which has had many regulatory problems. The UK FCA revoked his Mayzus Financial Services Ltd license as a payment processor in 2018. Mazyos was allegedly involved in Alexander Vinnik's Russian collapsed crypto exchange BTC-e as a payment processor. Mayzus seems to have legal issues in the Czech Republic.
