It's been 3 days and it is still unspent, most exchanges consolidate their deposit addresses' inputs daily (
or weekly).
Looks like you've sent your bitcoins to the wrong address.
Could be a fake clone site, was this your first time using Dream Market? If yes, double check the URL.
and transaction has been confirmed. 246 confirmations (not sure what this means) and says unspent next to the address i sent it to.
"
Confirmed" means that the transaction was included in a block, and I think "
246 confirmations" mean that it's already 246-blocks deep (
behind) from the newly generated block.
