its quite interesting to try. faucet too, long tine i didn't use faucet.
it was a long time ago, in fact, that a project did not use faucets to advertise itself, but i read that it only distributes testnet tokens, not the real ones, too bad...
I can explain how the Dusk testnet faucet works, because I already used it.
First of all this faucet is not like The Bitcoin Faucet from ye olden days which gave out 5 Bitcoin. Can you believe it? 5 real Bitcoin for free!
The Dusk testnet faucet can be compared to the Ethereum Ropsten testnet faucet and the Bitcoin testnet faucets: these coins are meant for development only and have no value.
Specifically, every day you can get 10 tDusk by tweeting your public address, which you get after creating a wallet through the Dusk node command line interface. You then have to copy paste the URL of the Tweet into the faucet. After a few seconds the 10 tDusk is added to your wallet. You can use the tDusk to test transactions, to stake or to bid. How to do that is described in the Dusk Blockchain repo README.
