I converted some SBD to BTC using blocktrades.us and asked blocktrades to transfer the BTC to a wallet on another site (a site where I want to convert them to real money), I did this 2 times before early this week, first time the transaction got confirmed in less then 5mins, 2nd time it took like 1 hour but now it’s almost 20 hours and nothing happened. I’ve read things on the internet that after some time you could lose the money (money being dropped out, since blocktrades sent the BTC from their own wallet and not mine if the money returns to blocktrades I think they are lost), or that a miner could help you confirm the transaction. Anyone knows what can I do?

This is the link to the transaction. (~120$ )

And if the confirmation somehow manages to work, what can I do to avoid this later.
