Quick question about difficulty on mining.

[carlitomayn]

Hi guys!

I've been involved with Bitcoins for a few months now, maybe even a year. I recently decided to get my first USB miner and have been using Bitminter to mine. This is just as a hobby for now and to see how it all works. When i started mining the difficulty was "50,810,339". Now i have realised that my miner says difficulty set to "65,750,060". I understand that this is because it's mining in a new block and difficulty increases but does this mean that the difficulty will stay at "65,750,060" forever or does it reverse back to the previous difficulty after the block is solved ?

Thanks.

The difficulty is adjusted based on how quickly previous blocks were created. The target is to have one block on average every 10 minutes. Roughly every two weeks, bitcoin clients look at the time between blocks for that period. If blocks have been coming faster -- like because more mining machines have been coming online -- the difficulty is adjusted upwards to slow things down again. I think the recent rise in difficulty is because a lot of people who ordered mining hardware a year ago are only just now receiving it. You should expect the difficulty to keep rising.

For the foreseeable future, it will just keep going up every 2016 blocks.  I am predicting that it will be around 600,000,000 by the end of the year.

Dif is adjusting evry 20 days (+/- 2-3 days) almost every time it goes up from 20-28% so.. btc will be to dificult to mine in near future..

The target is every 14 days but it is really every 10-11 days now.  Last was 8/13, this was 8/24, next is likely 09/04.

Next retarget is at block 256032.

This makes sence why there is such demmand for the USB block errupters

Um if difficulty is skyrocketing, why would you get a miner that already has an uncertain ROI timeframe?
