Coinbase added Dai stablecoin support in its debit card
The first stablecoin was added to the Coinbase Card debit card - it became Dai (DAI). According to Coinbase, Dai will allow you to pay for goods and services with less volatility, as its rate is pegged to the US dollar.
Dai became the 10th cryptocurrency added to the Coinbase card, along with Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Bitcoin Cash (BCH), XRP, Basic Attention Token (BAT), Augur (REP), 0x (ZRX), Stellar (XLM).
Coinbase management did not explain why Dai was chosen from all the many stablecoins pegged to the US dollar.
