You expect the company to be worth $10b at some point in the future, but the question to be answered is how much you think the company is worth today. Let's say you think the company is worth $10m now, which makes your stock worth $10k. Suppose the company then raises $90m in funding and gives the investors a 90% stake. Now your shares are only 0.01% of the company, and you think "Oh no, I got screwed by dilution!" But the company is now worth $100m, because it has its previous $10m worth of assets plus $90m in cash. So your 0.01% is still worth $10k.

What matters now is how the company spends the money. Hopefully they spend it smartly and the value of the company increases 10x. Now your stock is worth $100k. You didn't get screwed by dilution, you got a $90k bonanza because the company was successful.
