You're not going to get any investors. You're asking for $32,530-65,070 for something you don't even have a demo of.
The gambling market is quite saturated and you're going to need much more money to actually advertise your way to the top. Me and my team are progressing quite well with our site, which partially includes a coinflip game. I suggest working this thing out a bit more before asking for such large amounts of investments.
Do you think that investors expect a demo of a triple A title game before they invest into their parent company?...
As I've already said I'm looking for a way for the game to use a wallet without us having control over the investor's bankroll. And they can of course have a friend look over the code so they know it's not going to steal anything or be vulnerable to attacks. I can make the demo no problem, but I don't want to spend more time on this unless I have an investor. Otherwise I have studying and work on my current gambling project to do. Also you missed my reasoning for the "large" investment. It might be large for regular people but not for professional investors. My reason for it being large was because if the game does become popular nobody will play with such a low bankroll and if they do it's gonna take an even longer period of time to see some substantial profit.
No, but they do expect
something. You have the bare "minimum". Domain idea and the general site idea.
This is a horrible investment for anyone as you're going to have to spend $50,000+ for advertising if you want to compete with the larger sites.
Why would I use you over the sites that I'm already familiar with and trust?
What do you have to offer that no one else has to offer?
I can make the demo no problem, but I don't want to spend more time on this unless I have an investor.
Then you're not going to get an investor. If you do not spend your time making a demo you won't get any investor. No "professional investor" won't invest 50-100 BTC into something you haven't put into action, you don't have a demo for and don't even own the domain for! Just because they have a lot of money doesn't mean they will randomly throw it around projects which are bound to fail.
That's just my 0.00003025 BTC which is most likely the truth.
