I cant find any info on how to send XFCCoins directly from my online wallet to the DigitalTokens exchange.

my XFCCoin are in the online wallet https://wallet.footballcoin.io
I want to sell them on the exchange https://digitaltokens.io
for BTC and then send that out to my ledger.

can you explain how to do this, or what I need to do to get it onto an exchange to sell it. I am seeing all sorts of conflicting info about sending it into the game or getting it off counterpart or into a wallet or whatever. is there ELI5 instructions for the above anywhere?

thanks
