Right, but the dollar used to be relative to gold; then that changed and the dollar now fluctuates based upon amount of fiat printed (simply put). So while BTC is the standard NOW, what happens when it falls out of favor or there is a coup of multiple alts?

I would agree that BTC may be better to mine, but not everyone of us are mining.   Some of us are speculating and trading, so there are some ALTs that show great promise, at least short term...as the popularity rises, so does price.  Buy low, sell high.

So what makes BTC and LTC better than anything else?  OP states they are both "better supported"....well, going off that, if another alt is "better supported" wouldnt it overtake BTC/LTC? 

Its like saying you should only buy gold or silver, but not diamonds, rubies, emeralds, or oil futures or apple stock.  they're currencies and will be worth whatever the market provides.

what about 42coin that is worth what 100x BTC?
