1. Every altcoin has to invariably be pegged to bitcoin. So its fate is in some way tied to bitcoin. Until you have a coin big enough to exist independently and traded with USD, you are not going any where.
Not really, there are some coins that have direct fiat exchanging.
I'm not naming them though because I want to invest more in them first

Direct fiat exchanging doesn't mean they are not pegged to bitcoin. Their prices will be based on triangulation between XYZ/BTC and BTC/USD rather being a direct exchange between XYZ/USD. Even then good for you.
