Coinbase adds instant trading, and increases daily limits With the new trading restriction lifted, Coinbase is also raising the daily purchase limit for its tier of verified users to $25,000, up from the previous $25,000 weekly limit. New users chomping at the bit to start swapping for digital currencies or current high-rollers looking to push the daily limits should note that completing Coinbase’s identity verification, which requires uploading a driver’s license for U.S. users, is a prerequisite for either new perk.
