Buying coins is almost always wrong if you have cheap power.
Buying gear is almost always correct if you have cheap power.

Well from a simplistic BTC view, you'll probably never buy a miner that will mine more BTC than it cost to buy.
I purchase most of my miners with one year free credit.
And I can’t buy BTC on one year free credit.
But yea if you can’t buy miners properly (credit or cash) buy and hold btc is okay.In fact I recently cut a deal for a ‘free’ miner.
I take 2 from the dealer.
He gives me one
The other I let him mine for zero power cost for one year.
Thus no btc out of pocket.
no cash out of pocket.
Can only do this with cheap power.
better yet he repairs gear. So I get good repairs.
Our expansion issues are cooling.
Still waiting on the liquid coolers from octominer they are now sixty nine days late.
