When I view my Antminer and I see it found a block, is there somewhere else it will show me the blocks are done and I can reboot it?
Are you solo mining? If so yes good chance you got one (but its like winning the lottery).
If renting on some rental sites, or doing alt coins you might find one but it's not finding a BTC block most likely.
So really depends on where you have your miner pointed to.
