What to know about Tether and Cardano

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.

Cardano (ADA)

Cardano (ADA) is a Proof of Stake blockchain launched in 2017 and led by Charles Hoskinson, one of the co-founders of Ethereum. The project is known for its research-driven, peer-reviewed approach to development.

Risks and things to know

The ecosystem of applications is smaller than Ethereum's. The price is volatile.
