Hey crypto ray,
Thanks for the comment! Serving the unbanked is definitely an ambitious goal for any blockchain company to tackle straight out of the flood gates. However, I believe their initial product and roadmap will focus on cities that have established cryptocurrency hubs. This will build reputability and give the team a chance to fix any kinks or issues with their product. Localbitcoins.com is a centralized platform that allows crypto holders to buy or sell online or offline with fiat or other payment methods. They are used in unbanked countries already. Dether, hopefully, will be able to provide more online trading of assets as they develop their product and escrow system. Thankfully localbitcoin has given users a sense of security which Dether can take to the next level using the blockchain. Profitability will be determined by the transaction rate you charge. I believe people value their security, identity, speed of receiving the crypto (Coinbase can take up to a week), and protecting of earnings (for countries suffering from hyperinflation ) that they will pay a higher transaction rate.
