Once again I think you need to read SLOWER. I said I DONT think we will see 50% gain by the end of the week. To prove it I am willing to sell him 150 BTC calls. Those calls would expire worthless IF BTC DOESN'T RISE to more than $150 by the end of the week. I would profit under that scenario and lose (potentially massively) if BTC DID rise above $150 by the end of the week.
A 150 call wouldn't do me any good if I think it's gonna hit exactly 150. I'd buy a 120 call with a 1 week expiration, though. I mean, if you were a reputable options dealer and not a random guy on a forum.
Name a price and number of contracts you would be interested in (100 BTC blocks).
If I was a reputable options dealer I would direct you to my brokerage site. However I am slightly more than a random noob on a forum. You decide if it is worth the counterparty risk.
BTW $120 is a lot different than $150. I mean if the premium on a $145 call was low enough you could potentially collect a massive % if the price hits $150. The fact that you are now talking about $120 (which profits $120.01+ instead of $150 is a good sign IMHO. I guess I talked you down some.
