In real life, you'd see spreads like AMZN 04/13/2017 910.00 C 4.90 +1.67 Bid: 4.75 Ask: 5.20 (with AMZN @ $897 right now) and the fill you'd get on the buy side would be closer to the ask. i.e. I'd offer $5.00 and hope that it filled.  Filling a $4 bid when ask is $8 isn't likely unless the stock blipped down enough for your price to fill.  Options are a lot like day trading, in most cases.

Most long term stock 'investors' do well. Those who get in and out, not so much.  There are aspects to options that are appealing. As you've seen, the return can be high, even IRL, but your loss can be 100% as well.

A similar bet that ended a year ago yielded a 100% loss. I don't post there very often, as I keep that trading to a minimum.  There are warnings for those who want to start trading options -
