Glidera
Glidera offers an API to wallet developers which allows users to buy and sell bitcoin directly from their chosen wallet without having their money held in custodial exchange accounts. This also might help wallets find a monetization mechanism, as exchange fees, in the form of a spread, are shared with the wallet developers. However, Glidera allows only small purchases, and is primarily for beginners.
Accounts may be opened either with a standard manual inputting of details, or by scanning a bitID-enabled wallet’s (most notably airbitz or copay) QR code.
Once you’ve gone through this, and users must complete every step prior to even having a look around – you’ll be set up with a daily limit of $500, a monthly of $1,000. You can increase your limits to $1,000/$2,500 if you are willing to provide your complete social security number, answer additional identity questions, buy and sell $5,000 worth of bitcoin (so you’ll need to wait 5 months at a minimum) and wait at least 30 days.
