ESCROW is a must here. You cannot expect people to simply send you bitcoins upfront and hope you will fulfill your part of the transaction. Would you send the money upfront without the bitcoins? No, right? Put yourself in the shoes of the person holding these bitcoins. Would you send the bitcoins upfront to a stranger half way across the planet?
Are you aware of any trusted escrow service? Seems all companies are like anything else in this space, in a beta stage and/or completely unheard of.
Also, there is a chicken or the egg problem. How can I cashout and remit bitcoin to paper currency without having said coins in my hands?
I do not see any other way to have this system work without the sender's trust in my business. It's why I encourage to only send small enough amounts that make them comfortable. If there is any other way you could see to offload risk of both parties I would like to hear them.
Trust is the most contentious and challenging issue when it comes to transactions such as the type you are proposing here. What makes trust an even more important element of the relationship is when the agreement involves significant amounts of money.
The money remittance systems in the UAE and the rest of the Gulf region makes life so much easier for migrant workers and expatriate investors to move funds overseas. Far less hassle than the rest of the world, I admit. BitOasis as a Gulf-focused exchange makes this a potentially even more promising project for you and I hope you will find the financial resources and logistical support to turn this into a successful business.
The first step would be to find investors who are prepared to inject cryptocurrency resources into this project. This is a challenging step and it might involve you presenting a business plan and a feasibility study of everything from projected costs to expected gains (based on remittance trends in the UAE). Communication is key to everything and if you can successfully and properly communicate your intentions across people with significant disposable bitcoin reserves, then this might work after all.
And of course, you would have to consider the regulatory landscape in the UAE. I did read something about bitcoin ATMs being disallowed a a few years ago so I'm not sure how your plans stand against current restrictions and rules of the UAE government.
As for escrow, I'm not sure how you would approach this aspect, given the complex structure of a remittance system involving enormous amounts of money. I hope you will find suitable and appropriate advice about this.
Is BitOasis already involved in remittances?
