did anyone calculate if it is better to just buy the crypto outright vs mining for it? Equipment cost plus operational cost (electric and aircon).. what's the expected ROI for mining?
it depends actually. if you want to buy and HODL, let say u got rm10k to spend
RM10k can get you around 9 eth, you hold for a year, price rise from 300usd to 400usd, u sell it all, you get around 100usd per coin. (Let say)
RM10K can get you 6 gtx1060 6gb mining rig, with the current difficulty, you can get around 0.6eth per month, in a year, you will get around 7eth, 1eth = 400usd, so total is around 2800usd
BUT,
u need to minus around rm100+ for electrity each month
difficulty will kept on increasing each day so u cannot accurately predict your profitibility, just like i did here
metropolis started already, mining will get harder for sure, BUT eth price will increase (?)
if mining rig, you can sell it back and get 60-70% of your rig price
either way, so many variables. so to answer your questeion, no one can accurately calculate which one are better. 3 months ago ROI is around 3-4 months, now its about 10months, next month, who knows.
