The Coinbase Bundle product has been deprecated, per an FAQ on the cryptocurrency exchange's site. All cryptocurrency balances that users obtained via Bundle purchases have been placed into the respective asset wallet in the Coinbase user's account.
Coinbase Bundle was launched in September 2018. The product was intended to make it easy for users to purchase a market-weighted basket of cryptocurrencies with as little as $25. At launch, the Bundle included the 5 cryptocurrencies listed on Coinbase: bitcoin, bitcoin cash, ethereum, ethereum classic, and litecoin.
