Hello there!
As any saving account, bsave is not designed to pay interest on cents and requires a minimum in the account to be able to pay the minimum of one bit of interest on a daily basis. As the bsave rate fluctuates, the minimum balance required to accrue interest range between 0.05 BTC and 0.1BTC.
The reason why there is a minimum amount required that may be withdrawn is because we are paying the mining fees on behalf of our customers. As a consequence, there is no fees paid by our customers to withdraw btc. It would not make sense economically if we had to pay 400 bits to miners each time a client withdraws 300 bits.
We understand a lot of scams undermine businesses trying to add value to the bitcoin ecosystem and there is no such a thing that getting paid interest without trust involved. We also understand building trust takes time. And ultimately this is our biggest challenge.
As bitcoin is deflationary by design, earning deflationary interest on deflationary money is something amazing on a long-term basis in our opinion and we are proud to have built a system that paid interest to our customers on a daily basis since November.
