After mining for a week and seeing 0.41% daily ROI (149.06% annual return) I decided to buy additional 10 MH/s lifetime Altcoin contract for 0.5261 BTC (179.90 USD).
Now after 24 days of mining and seeing 0.31% daily ROI (112.32% annual return) based on the average ROI of the last 7 days of mining, I am thinking whether I should buy 100 MH/s for 3.9574 BTC (1499 USD) or just buy BTC and keep them.
ROI calculation is based on BTC only, not taking into account BTC/USD rate.
Link to the actual spreadsheet in iCloud, regularly updated: Genesis Mining.numbers
Explanations of the fields:
| Date | Date and time when BTC were spent (sent) or received from mining |
| Type | Sent: miner purchased, Received: BTC received from mining |
| Amount | BTC amount spent on miner purchase or received from mining |
| Total | Total amount of BTC received from mining |
| Duration | Time lapsed in days, hours, and minutes from the previous BTC reception from mining |
| Ratio to 1d | Ratio of duration to 1 day (=1 if Duration is equal to 24h, >1 if Duration is > 24h, <1 if Duration is <24h |
| 24h Norm | BTC amount received from minining normalised to 24h period |
| 7 Day Av. Norm | Average daily BTC amount received from mining for the previous 7 days |
| Daily ROI | Average daily return of investment on BTC amount spent for purchasing the miners (in %) |
| Annual ROI | Annual return of investment on BTC amount spent for purchasing the miners (in %) |
| Total ROI | Return of investment so far vs. amount spent for purchasing the miners (in %) |
| Days to ROI | Days left to reach 100% ROI based on BTC amount returned so far and previous 7 days of mining |
| ROI Date | Date when 100% ROI is going to be reached based on BTC amount returned so far and previous 7 days of mining |
So far I received 5.59% of BTC invested.
100% ROI Date is being pushed into future, and I have a concern it will be pushed indefinitely with Altcoin difficulty increase.
What would you do in my shoes: buy more mining power or just buy and keep BTC?
(let's try to leave any irrelevant discussions, such as whether Genesis Mining can disappear or what happens with BTC/USD rate, outside of this topic)
