What to know about Tether and Bitcoin

Tether (USDT)

Tether (USDT) is the largest stablecoin: a token designed to stay at one US dollar. It was launched in 2014 by Tether Limited, which issues USDT against reserves that consist mostly of cash equivalents and short-term US Treasury bills.

Sending and receiving USDT

The key choice is the network. USDT on TRON is popular for its low fees and speed, ERC20 is supported almost everywhere but costs more in gas, while Solana, TON and BEP20 are cheap alternatives. The recipient address must belong to the same network you send on, and you need the network's native coin (TRX, ETH, BNB…) to pay the fee from your own wallet.

Bitcoin (BTC)

Bitcoin is the first cryptocurrency. It was described in a 2008 white paper by the pseudonymous Satoshi Nakamoto and launched in January 2009. Bitcoin has no issuer or central operator: the rules are enforced by thousands of independent nodes, and the supply is capped at 21 million coins.

What Bitcoin is used for

Bitcoin is mostly held as a long-term store of value and used as the base asset of the crypto market: most trading pairs, indices and derivatives are priced against it. It is also used for cross-border transfers and, through the Lightning Network, for small fast payments.

Optimism network

Optimism is an Ethereum layer-2 network. Addresses use the Ethereum format and fees are paid in ETH at a fraction of mainnet cost.
