I would mine using the gear I have.
I won't be buying gear at current prices.
Here is the funny thing 23k is about right price for mining profits of BTC.
100 th earns 100 x .1612 = 16.12usd
if it is 40 watts a th it is 4kwatts x 24 = 96 say 100 kwatts a day at 6 cent power that is 6 bucks a day
so 16-6 = 10 dollars a day at 6 six cents
8 dollars at 8 cents 312 days to roi
9 dollars at 7 cents 277 days to roi
10 dollars at 6 cents 250 days to roi
11 dollars at 5 cents 227 days to roi
12 dollars at 4 cents 208 days to roi
13 dollars at 3 cents 192 days to roi
14 dollars at 2 cents 178 days to roi
if you have 2 s17s. they cost about 1250each or 2500
2500/14 = 178 to break even at 2 cent power
the numbers above are reasonable numbers for asic mining of btc.
Now eth with gpus.
say a small 75mh rig for 825
75 x 4.07 cents = 3.05 a day pulls 285 watts or 7kwatts
3.05- 1.05 = 2 bucks at 15 cent power
2.00 at 15 cents 412 days to roi
2.07 at 14 cents 398 days to roi
2.14 at 13 cents 385 days to roi
2.21 at 12 cents 373 days to roi
2.28 at 11 cents 361 days to roi
2.35 at 10 cents 349 days to roi
2.42 at 9 cents 342
2.49 at 8 cents. 331
2.56 at 7 cents. 322
2.63 at. 6 cents. 313
2.70 at 5 cents. 305
2.77 at. 4 cents. 297
2.84 at. 3 cents 290
2.91 at 2 cents. 283
at first glance asics look quicker to roi, but they are loud they are hot they need 240 volts. they have shit warranties they have poor resale or spotty resale
gpus 2 or 3 years warranties transferable
quiet
better resale
I have blended my mining for years doing gpus and asics. I also resell a lot of my gear. So I do not clock the shit out of them.
Right now I see upside for eth it is not close to its all-time high of 1200 or so.
BTC is getting close to the July 2019 level of profit if you factor in:
the diff
the 1/2ing
more efficient gear
price
we could not hold the July 2019 price of 13k I think if we push to 28-30k we won't hold it.
Eth looks like a better play. BTW fuck eth I don't like it. I dump all my eth to cash and btc. But it looks better on paper at this moment in time than btc.

Hashrate watch this it is at 281th
If it spikes like mad to 325 or 330th it means a shit-ton of eth asics went on line.
It is why I do not like eth. I feel they could fuck with asics and they do not.
