Please stop putting words in my mouth.  I never said BTC was Visa, nor did I say it was Paypal.  I also don't think I am "wasting" BTC on my purchases.

Every single bit I spend I buy back, immediately, to replenish my stock.  I spend Bitcoin to support the network (there would be no miners if there were no transactions to confirm) and because sometimes you get great deals, like Purse.io.
