Not sure if this is the one, but it looks like they rebranded or moved to "The Cardano Foundation". Their site, adacoin.com, now links to cardanofoundation.org. Honestly never heard of this coin, as it's not even listed on coinmarketcap. I personally don't trust it, so I suggest that you proceed with caution.
Here is plenty of reason more not to trust it:
https://medium.com/@classicether/out-of-the-ether-a-crisis-of-irresponsible-governance-facing-ethereum-classic-a77abdd7a9faThe ICO has to be some kind of record holder in terms of shadiness - they kept it behind closed doors in Japan and held the BTC until they appreciated majorly with no communication in the meantime for months!
ICO price was 0.0025 USD! This was supposed to be a well kept secret until the ambush listing came on Bittrex. It's scam through and trough.
with more types of information like this people will be more eager to learn about what really happening behind the scene as we seen a lots of big movement
from its certain trade and holders and believers are already gaining a lot, people love to seek for possible chances so even there's already a bad information
they will still willing to take the risk and ride for a while taking chances from the time being when the value still showing strong and newcomers are playing around.
