1. Build a DEX.
2. Sell it.
I can't access the site though, it is still not registered on any DNS?
If the OP hasn't decided on a use, he wouldn't have pointed it anywhere DNS wise.
I'd probably look into building an exchange to swap between cryptos. BTC->ETH, etc. If you need any help with building it, let me know.
If you don't have the funding to build out an entire site, I'd look into selling the domain name as mentioned. It's a good name and someone who really wants it would probably give you a reasonable amount.
