Why? Mine is in my signature. All you can do with a public address is send funds to it. We are not asking you to post your wallet.dat with password, lol.

Just post a screen shot of your coinmarket.io account with transaction ID and the incoming fund from your wallet. This would put a LOT of people at ease, if you did this you would be doing a great service to coinmarket.io. The problem is, everyone who says they have received their Bitcoin is a new user with 1 post, and they all say they do not want to post proof because if they post their Bitcoin address it will get hacked...

This has to be the dumbest scam strategy I have ever seen. Why would you come on to a forum of cryptocurrency experts and claim that you do not want to post your public address because that means your wallet will get hacked? How dumb can you really be, scammer? You don't think we will call you out on this rubbish? If you posted that on some random non-tech forum, or if it was on national news etc then maybe you would get away with it, but at a tech website that specialises in cryptocurrencies, lol, you have no chance trying to fool people with this utter nonsense and deception.
