Bankera is a spin-off of SpectroCoin, which is a wallet and exchange.
Problems:
1. SpectroCoin has an opaque fee structure. Particularly, they are not transparent of their exchange fee. After using their exchange service, I calculated over 4%. Which matches the statements in this 2014 CoinDesk article
https://www.coindesk.com/spectrocoin-launches-bitcoin-cash-service-25-countries/Such a fee is terribly exhilarating.
The card mechanism and charges are not clear either. You need to get in touch with their incompetent support to get some information.
2. Banking is science, notably nowadays when compliance and regulation adherence are filled with intricacies, and fees are numerous and sophisticated. Their support is simply unable to assist. Their agents are oftentimes off-topic, they are slow, their contents are poor. As soon as the matter gets complicated, they just don't know how to help. They are bored and unmotivated.
Since Bankera is directly related to or identifies with SpectroCoin, then these problems should raise some serious perplexities.
