How to transfer bitcoin from different wallet to steemit

Hi guys,

I transfer my few bitcoin to steemit address, The steem address I got from buy clicking the Get New Address button in blocktrades web page. When I click the buy steem it redirects to blocktrades page, I got the address from that and I transfer my bitcoin to that address. I don't know why I still didn't receive my Bitcoin. I was thinking of converting bitcoin to steemit. Still not received. It's been more than 6 hrs still not recived some one can guide, how I can check it
