We cannot buy or sell a coin on any platform we want. It should - first of all – be included on the relevant platform and its wallet should be operational. To find out on what platforms we can buy and sell a particular coin, we follow the following steps:
• We visit the "Cryptocurrency Market Capitalization" website (https://coinmarketcap.com/)
• We type in the "Search" field the coin we are interested in (let's say this is Verge -XVG). After selecting our coin, the site redirects us to the page containing information and statistics for this coin.
• We move to the Markets field and, apart from the platforms where we can do our trading, we also get extra information about what Base Markets are there for that coin and its trading volume.
