I totally agree with your premise. Most of the "money" going into bitcoin will be from within the crypto sphere, not from the outside fiat world.. If the trend continues I want to buy my favorite alt coins just before the forks, which I assume is when the bitcoin price will be at its highest.
Since I buy the alt coins with bitcoin, it is the prefect storm. I get to buy bargain coins, with inflated ones. I am working on my wish list as we speak. But I will wait to pull the trigger as I want the best prices and I want my bitcoin to stretch the furthest .
If the alt coins make a quick turn around, then I will just hang onto my bitcoin and take the free coins. Maybe I will put in some crazy low ball orders now as anything can happen in crytpo land. Time will tell.
