Coinbits

Coinbits is a bitcoin savings app for US users that links everyday spending with regular purchases: after connecting a bank card, each purchase rounds up by a chosen percentage into bitcoin, and users can also set weekly or monthly fixed buys, with assets held by a partner custodian.

The product treats bitcoin as a long-term savings vehicle rather than a trading instrument, keeping only buy, automatic buy and withdraw, with no high-frequency trading surface. Licensed custody and banking rails handle fiat in and out, and customer funds are segregated from operating funds. An option converts cashback into bitcoin, turning payment flow into holdings. It started in 2017 as Bitcoin Roundup and later took its current name.
