I have been able to try out a new company like that where a newly content creator by name Joshua Bolu...is their ambassador, Assetar been the company claims to trade crypto and gift cards to Naira. I followed up their site but all the transactions was done manually on Whatsapp by the sales manager. As in, you'll be redirected from their site to the WhatsApp number for business.
Although, I don't find it safe dealing that way because most of the company are just owned by individuals operating from their rooms, no office while some are not registered.
Oh wow, Whatsapp transaction doesn't look or sound professional or at all. They need to invest more on branding. Most people try to build on integrity alone forgetting branding is a major part business, the difference between chicken republic and some local restaurants we patronize is not just about the taste is branding, Some local restaurants food might even be better than the chicken republic yet we are pay higher. A reliable and secure app or website where transactions can be made would have increased the trust they get from clients.
