I don't even know if those coins that they've made has its own blockchain to check the transactions. Probably, most of those doesn't have and it's just moving on their own exchange.
They have but it seems it's under ddos attack take a look at their explorer here
https://yoscan.io/#/ it keeps loading when I accessing it. So my guess it's under DDos attack.
I just found it from coingecko and they currently have small volume yet and 2 exchanges that support this coin.
Thanks, I've visited it but it doesn't stop loading on my end too and suddenly the page errors, so I think that this is no longer working anymore. I've looked also on coingecko and I found coinsbit and bitforex having this coin.
I think they're already preparing for the massive buys whenever this airdrop starts.
