KYC is required when using regulated exchanges with fiat on-ramps. You don't need to trade on exchanges that implement KYC, but the exchanges that are compliant are normally safer.
We don't have to because we have an option, Binance is a big exchange and regulated as well but they give an option for traders to trade with KYC, and majority of the traders can enjoy it and at the same time, they will feel safe as they are trading in one of the biggest exchange is not the biggest.
I trade on ecxx because it uses ledger vault cold storage, is located in Singapore and is regulatory compliant, and is backed by a 44 million dollar funding round.
Well, I really have no idea about this exchange, must be a big exchange as well since they are back with 44 million dollar funding.
Can you explain further about this site? This is interesting.
