The social send project was made to simplify the sending and receiving send token across borders via social decentralized network they have been performing so poorly in my opinion.
The social send exchange is a centralized exchange, which allows you perform only three functions successfully which is the send, trade and receive coins. The platform is not of good quality first of all by looking at it user interface design it is so much jam-packed and looks like a 1960 website. It actually looks like a like an abandoned project to me as there has not been any update of the user interface for so long. Though there are a lot of coins for you to trade, but most of the is done only with crypto to crypto pair. There hasn't been any update or inclusion of a Fiat currency. For my own point of view I wouldn't advise you to you invest in such a project as it hasn't been worktop on for so long. I recommend you look for other options
