This is purely down to my own ignorance but I have known that CEXs charge spreads, almost since I started using them, but I never actually checked the spreads until yesterday.
So I was on robosats doing my monthly DCA to try and scoop the dip, and the premiums were about 6% for my currency pairs. I understand the extra privacy premium but decided to see what Binance premium was, as in my head, I was sure it was way cheaper, like half a percent. I don't know why I thought this, I just did (they hide it in there quite well).
Anyway, turns out the Binance premium would have been 4% - that's crazy for a kyc.
now sure other exchanges might be lower, but they're kyc too
Paying that extra 2% for non-kyc really is a no-brainer.
So yeah, if you have ever been put off my non-kyc buying for spread reasons, you shouldn't be.
Plus later in the day when i checked, not only had btc dipped more, but the spreads were down to like 3%, alas, i had already done my dca by then tho
