To map the worldwide crypto scene is an impossible task. One encounters a practically opaque network of crypto exchanges such as Binance, ByBit, KuCoin, BitGet, etc., and connected payment processors such as Advcash or MoonPay. For example, the FIAT transactions of the crypto exchanges are processed via the latter. Of course, this is a very simplified representation. But you have to start somewhere. The "101 Crypto Ecosphere" chart shown above is such a start.
