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 -

I never recommended buying this just to be clear to anyone reading this. Someone asked me for my thoughts on buying it and what I foresee this miners profitability medium to long-term to be like
This is what I said
"I cannot give financial advice, and I really struggle to recommend any specific miners in the tough world economy state as well as somewhat prolonged cryptocurrency bear market. However I dont think that the bitmain antminer K5 is a bad buy but I am still confident in my estimate that with a residential electric rate and no crazy CKB price movements youre likely to breakeven on this miner purchase in a year.
Breaking even on crypto mining hardware is really appealing to some people, and not appealing at all to some others. Its really up to you and what level of financial risk you want to incur."
