You could have bulk purchased a while ago for less than that. Also if you use that logic (which is beyond any common sense), buying bitcoin is always better than buying mining equipment.
Sure at certain points in time it would have made sense or makes sense.
But whats wrong with my logic there? I look at the price of mining equipment in BTC (or whatever altcoin i want to mine), then i try to estimate how many coins i will get from mining. If i would get fewer coins back then i spent on the mining equipment its a bad idea. Simple as that. Otherwise you spent coins to "enjoy the luxury of mining".
