Dilution is a red herring. It doesn't change the value of your shares (theoretically). What will matter is how the company spends the funds that it raises, and whether it does so in a way that generates a positive or negative return on investment.
With no dilution my stock is worth $10mm (minus taxes, strike price, etc.)
With 10% dilution per round and 4 more funding rounds, it's now worth $6.5mm.
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.
