Firstly I see no reason why someone on this forum that has ranked enough to be in a signature campaign would receive bitcoins directly to their exchange address and worse of it all a centralized exchange. With all the endless threads and discussion about privacy and decentralization I think it's high time many were already properly informed about these things.
There are alot of things to be learnt from discussions here and the least and most of recurring of them all is the gist concerning privacy and decentralization.
I do agree, I can't fathom that someone in a campaign is using a centralized exchange to received their payment? We can simply created a electrum wallet for ourselves and I think most of us are doing that because want to have control of our Bitcoin. In this case, if it is flag down then the only way is to explain it to Kucoin or any other centralized exchange if this is the case that he is getting his Bitcoin from a campaign or it is a payment weekly to him. Hopefully, he has learn his lessons here and can get back his one week of funds from Kucoin exchange.
