Since everybody knows what people mean by saying stuff like "I reached my ROI" it's not going to change anytime soon.
For US members, there is another reason why this comment is a waste of time, we could have discussed other financial stuff like tax consequences and received the input of the finance experts.
I'm not a tax or finance person but for instance, when I put together a miner, from my previous work experience as an engineer, not only are the miner components capitalized, but I believe the total LABOR hours in assembling and making a miner work is a capital expense associated with the assembled miner and depreciated in the same way that the sum of the miner components are.
