I had different exchangers, but all had high commissions. I managed to find a good and safe option. It is WhiteBIT otc crypto trading platform https://institutional.whitebit.com/otc .
WhiteBIT’s OTC service is built with high-level trading needs in mind. Institutions, family offices, and HNWIs benefit from a high-touch service with dedicated support, personalized trading solutions, and a robust infrastructure capable of handling the demands of professional capital allocators. I recently tried it and was satisfied. Everything is very fast within one day.
