On January 21st, during the North American Bitcoin Conference in Miami, BSAVE announced its Bitcoin savings account for Coinbase wallet users. This new feature allows Coinbase clients to receive daily interest payments.
That smells like a scam.
The article is misleading. You don't get interest on Coinbase deposits like it implies. You have to send your money to them. Also, if you read the errata at the bottom, you will see that Coinbase cut off their API access.
