I just decided to buy some Tether stablecoin to deposit at a casino but the exchange is asking if I want to send it an ERC-20 or an TRC-20 address? What the hell is that? They say if I make a mistake the funds will be lost and I won't be able to recover them. I thought stablecoins were supposed to be less confusing than bitcoin but this all seems very complicated. Can someone please explain what this is all about?
