why are binance prices so low
In part, Binance may have lower prices due to the size and reputation of the exchange. Since an enormous amount of currency is traded on Binance each day, the prices of coins can be somewhat lower than they are elsewhere. However, one should not confuse prices listed in Tether (a currency that is backed by the U.S. dollar) with prices listed in dollars.
If one confuses the two, it may give the illusion of lower prices on the Binance exchange. Sometimes, prices on Binance can be genuinely different from prices on other exchanges. It is not always due to a misunderstanding of the price differences between Tether and U.S. dollars.
