Omg I'm so confused. Sorry for not mentioning binance.us in the OP. I've always been using binance.us for many years and the btc, eth, and all other prices have always been consistent. Why are they lower now?
Regulatory hurdles. Do a quick Google search on Binance US to check their recent issues.
Check out Binance US' BTC/USDT(Tether) pair — it's far more on-par with bitcoin's accurate price.
