Hes offering a coin to the first ten people but the coin does not come with any BTC attached. It is just a gold plated BTC looking coin. No actual BTC value. Still, could easily be a scam.
Yes the coin is physical without BTC attached. It's a souvenir/gift because you were from the first people that placed a bet. But the prize will be real 1BTC..
I know that it may look suspicious and many people will think it's a scam like you. But when we give the 1BTC to the person that bet 0.01BTC it will be a priceless moment for him and us if he shares.

if you bet 0.01 the odds are 1 of 110
We passed the 10 bets but still if you want one place a bet and we'll send you one

It's like you're buying it but you have the chance for the prize.
