When I first got to know this exchange, YellowCard, the name unlike other exchange sounded very funny and unserious but when a friend of mine introduced it to me, I was shocked and since then, YellowCard has been one of my exchange I use for trade in cryptocurrencies. From my experience so far, YellowCard has been very easy to use, what made it easier is the fact that it is available in many African countries which includes my country, Nigeria.
Operating on this exchange has been very easy and simple to me. Signing up for an account with YellowCard isn't difficult at all, all I did was to provide the necessary information they requested for, also on the first day of my trade on this system, I was able to access some educative informations on how to purchase, trade on this exchange and there are even more informations other than the ones I accessed. It allows purchase of cryptocurrencies available on its platform with many options but I only use bank transfer. However, YellowCard does not support enough cryptocurrencies for trade but at least it supports the major cryptocurrencies like BTC, ETH and USDT.
Finally, I strongly recommend that everyone especially those in Africa to use this exchange as it is even available as a mobile app.
