Coinbase is the most popular online wallet in the world.
It's easy to buy, sell and store Bitcoin, Bitcoin Cash, Litecoin and Ethereum currencies safely.
You can link the wallet to its bank account (SCT) to buy currencies or convert currencies in euros or dollars.
Bitcoin, Litecoin and Ethereum addresses are generated automatically for you to assign a label to each one : and when paying, you can more easily identify the source of payment bitcoins.
A mobile application (Android or iOS) is available to facilitate the purchases/sales bitcoins (scan QRCode).
For merchants, buttons or payment solutions are preconfigured and easy to implement.
There is now a referral system. When your friend buys or sells 100 $ of digital currencies, you both will obtain 10 $ of bitcoins for free.
