D3 and K5 are not comparable, with D3 you had 100+ coins/chances to mine and hoping that one of them could gain price and make roi (luckilly my case)
K5 is only for CKB, but that could change, maybe more coins will occur on nervos algo
What coin did you mine, that gained price, that allowed you to breakeven or even better on your antminer d3?
Dash was the ONLY coin worth mining on X11, then,now, ever whatever, imo
Speaking of the Bitmain Antminer K5, my miner mined 2600 CKB coins in 24 hours if anyone wants to read about it / hashrate logs etc -
https://voskcointalk.com/t/analyzing-mining-profitability-of-our-bitmain-antminer-k5-nervos-ckb-asic-miner/210at that time I put quite a lot of time in x11 research, if I stayed mining dash, roi would newer happen and to be honest it would be boring mining only dash with such variety of coins back then
I tried mining at least on 50 x11 coins, most of them are unknown, some of them forked to pos and mn (polis, monkey, centurion before fork and after fork to equihash it was gold mine)
i was up to mine newest coins (pow and mn) and sell them, becacuse price was higher and folks bought them for creating masternodes - mostly of them were more profitable than dash, but that lasts only for a couple of days, than I moved to another coin
I spend a lot of weeks mining imagecoin (and imagecash) and in some time frame was only one mining it, I mined 40000 IMG, created masternodes, and at ATH sold one masternode (10000 IMG) than bought it back when price fell - that returned my d3 investment 2x
That’s interesting, glad it worked out for you and thanks for sharing the information
