What to know about Bitcoin and Tether

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.

Sending and receiving BTC

Bitcoin addresses start with 1, 3 or bc1. The fee depends on how busy the network is, not on the amount you send, so wallets let you pick a faster or cheaper fee. A payment is usually treated as final after several confirmations; each new block adds one, so a transfer takes from about 10 minutes to an hour.

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.

How Tether works

USDT is not a blockchain of its own. The same dollar token is issued on many networks — TRON (TRC20), Ethereum (ERC20), BNB Smart Chain (BEP20), Solana, TON, Polygon, Arbitrum and others. Tokens on different networks are not interchangeable directly: they are moved between networks by exchanges and bridges.

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.
