I get what OP is saying and I somewhat agree. This is an extremely basic example of what he is thinking of:
Let's pretend you didn't have any coins. 450$ in BTC will get you about 1BTC. 450$ gets you roughly 1,000 PPC. If trends continue, PPC is roughly about 0.1% to 1.0% of the BTC price (Roughly 8$ during the 1,200 peak). If Bitcoin were to hit 10,000, and Peercoin hit 1% of that (100$/PPC) your 1BTC would yield 10,000$, while your 1,000 PPC would be 100,000$. Granted it is a higher risk than BTC, but you don't need PPC to hit the moon, you just need for it to do mildly well.
Regardless of your feelings on altcoins, 100$/coin will someday not be a huge fantasy, at least for those in the top ten. The yields are better, but the risks are higher. Investing in the more reputable coins (if there is such a thing) I think is a reasonable investment. Replace PPC with any other coin, I'm not trying to single that one out. Please refrain from bashing, I'm just trying to share my thoughts.
Edit: I'm not saying go all in on altcoins, however much you feel is sufficient should be fine.
