Apples or shmapples, nothing changes the fact that spending bitcoins buying dollars is not the way to go for a bitcoin believer.
"Believing" in bitcoin is not a legitimate reason for trading irrationally.
If you see a trade of zencoin for bitcoin (or vice versa) as having anything at all to do with dollars then you are missing the whole point of relative valuation to begin with, and no argument will be likely to convince you of your mistake.
Pretend USD and other fiat currencies never did exist. Does your reasoning still hold? There is no reason that it shouldn't, if it is sound.
I've explained it twice already.
You either get my point and agree, or get my point and disagree. The bottom line is if the btc gonna cost 1000$ next year then I could buy X3 times the amount of process power / service on Zennet than I am now with the same btc.
Of course no one stops you from investing your dollars and I didn't say it is a bad idea, what I said is that spending btc now could cost you in the long term..
