This thread is due a major update, however I have made only a small important update.
Universal WalletsCopayCopay is a Bitcoin wallet by Bitpay and available on iOS, Android, Windows Phone, Linux, Max OS X, and Windows. Because Copay is available on multiple platforms, it’s easy to use the same wallet or accounts across multiple devices.
Copay’s simple, clean user interface makes it a good choice for new Bitcoin users. Copay is also a good option for businesses due to a shared account feature, which requires a certain number of users to sign each transaction. Two co-founders, for example, could create a 2 of 2 wallet where both will be required to sign each transaction.Copay and Bitpay are NOT recommended wallets due to their anti-Bitcoin stance and behaviour (which also includes many terrible technical practices, refusals or intentional delays to implement support for functionality that users could benefit from)..
The backlink to Copay has been removed and they are no longer recommended. In the next update they will go into the list of wallets that are strongly not recommended.
