Ethereum is quoted to two decimal places on every virtual currency exchange, and almost nobody stops to ask which number they are actually looking at. There are at least four, they differ by more than the trading fee, and the gap between them is where retail traders quietly lose money. If you are setting up an account to trade ETH, my referral code is BBBKK at https://www.binance.com/register?ref=BBBKK - roughly 20% off spot fees - and the verification step described near the end of this article is what actually makes that discount exist. Skip the verification and the code is worth nothing. Now the four numbers.
