Hi all, Our company is looking forward to hiring a reputable software development agency that can help us build the American Express for Bitcoin. This implies that we will need a Bitcoin wallet and a Bitcoin card [virtual & physical cards] that our consumers can use to spend online and withdraw fiat currencies from local merchants worldwide. The wallet will come as a mobile app for Google Play & Apple Store, while the card will have the company's brand instead of the current card networks in the market i.e. Visa, Mastercard, etc. This is a full-stack project and all we have is the above project description. So, if you're interested and are capable of implementing the project, kindly share similar projects that you've done in the past, place a bid with a budget within the budget range and delivery time, and we will get back to you if there's a catch Best regards, W.
