Waterhole is not a website !
It is a mobile app, You can download it from ios app store or google play.
I have 100+ bitcoins
Sorry but I am not using that unknown website.
I currently have $364 so give you your best BTC offer.
Sorry but I won't use an unknown thing such as that.
You can either go first or use escrow fees on you.
I will buy all btc you have for how much ever 364 can get me.
