Tailored for the American and European markets, Circle is a bitcoin wallet and former exchange.
The Circle app syncs with your bank accounts, making for seamless transactions, and improved organization of one’s funds.
The Circle App is the first bitcoin App to introduce the message integration feature, and so, bitcoiners may perform transactions using only SMS without connecting to the net!
The Circle App, unlike many other wallets, charges you zero to move money, and there is no limit to how much you can send or receive or cash out on weekly basis.
Unlike Xapo wallet, Circle is praised for the kind support it has.
On matters security, Circle performs poorly, though.
It lacks important features like: hierarchical deterministic, two-step authentication, and multi-sig!
Badly enough, the wallet is not open-source.
