Pretty much all coins have a CLI. The only coins I'm aware of that ONLY have an official CLI (no GUI) are Ethereum and Monero.
wait wait wait..
let me .... drink this in.... for all its worth.....
Monero.... doesn't have a GUI... gets constantly ... trolled... for this.
Ethereum comes out... has an ICO / premine / something-or-other, jumps up to a 96 million USD market cap.. and its CLI only?
thats just.... Beautiful. I want to give everyone high fives here.
Sorry for the derail. I just couldn't resist. Maybe in all of these newly cropping Eth = scam pages someone has mentioned this. Do i wanna wade through that stuff?
