Title: How Much is a 50 GH/s BFL Bitcoin Miner Worth Post by: mamutin on October 11, 2013, 04:33:32 PM How much is a 50 GH/s BFL Bitcoin miner worth if it starts mining
at the 20. of October 2013. Normally the difficulty is increased every 2016 blocks. Which is about 14 days. Szenaria with Current Difficulty Increase The difficulty increase is calculated with 30% over each time frame. This is the current increase per time frame.
This is about 140$/BTC x 6.17BTC = 863.80$ Optimistic scenario The difficulty increase is calculated with 20% over each time frame.
This is about 140$/BTC x 9.25BTC = 1295.00$ There is no energy cost calculated an no service charge. If you will subtract this there will not very much left. So what can you do? Trash on delivery for the darkness of surroundings … There is a thread, how to get a refund https://bitcointalk.org/index.php?topic=295187.0 May be that helps.

How about 30% for the next two periods, then 20% after that?

Normally the difficulty is increased every 2016 blocks. Which is about 14 days. Szenaria with Current Difficulty Increase The difficulty increase is calculated with 30% over each time frame. This is the current increase per time frame. The difficulty always adjusts at exactly 2016 blocks. If you are estimating 30% difficulty increases, then those 2016 blocks will take about 11 days, not 14.

However some people might use it to mine other coins so your calculation does not take this into account. Also what is the life expectancy on the device? Will they really last 2 yrs of continuous use? But yes mining is becoming a mugs game...so much for the decentralized network. If btc is worth $500/usd in 2 yrs then you would easily be in profit.

I already 100% ROI'd on my Block Erupter USBs by mining and holding PPC with them before the price doubled. :P The "will never ROI" statements are silly to me.

Title: Re: How Much is a 50 GH/s BFL Bitcoin Miner Worth Post by: ralree on October 13, 2013, 04:19:52 PM I still think using a percentage to scale the difficulty constantly is silly in the long-term. Sure, the hashrate will grow 30% each month (at least) for a few months, but I think we'll see a flattening, then another increase from various manufacturers around the end of the year, then another flattening. It's anyone's guess though - interesting analysis - thanks for posting.

This is just plain gambling. What if PPC failed to rise? What if you bought them for a sum you've spent for erupters? The "never ROI in BTC spent" statement seems to be pretty much true if the network continues to grow like insane and outdated devices get sold for BTC w/o accounting for network growth factor. |
