If we get negative then problems follow
If we remain positive then good things happen.

Bitcoin is now an international economy not just a currency. Swings will happen. The trick is to be in the right place to take advantage of these situations.

and by the way since im on this forum and im mining im just as much apart of this as anyone else i have invested interests as well thanks , BUT i wont convince myself about things that are not true. ive spent along time researching bitcoin the system the maths , and it dosnt look good i feel the small miner upto someone running 250Ghash has a problem ? if Thash system flood the market and i bought 10 of them as a small miner what dose that make me ? A small miner who has spent £10,000's who will loose his investment in a year when the 50Thash boxes are built and released , and then the 200Thash boxes have been released , talk about shooting ya self in the foot , AGAIN Prove me wrong with facts and maths not just your opinion please, im not being negative im just looking at this with out my rose tinted shades on , and im sorry for this

im talking about the jump in speed and tech, satochi said bit coin would take until 2140 to be complete ! its now something like 2040 becuase of the speed in which we mine , we are mining our way out of bitcoin, the change you speak of didnt have big company's producing massive power crunching machines, im saying the tech has shot us in the foot. im just trying to have a VALID opinion of the situation, so dont drag me to the wolves for it, once we can see whats really going on we can work together to find away we can continue , Problem Action Solution

Is this post fair ?

are you mad!!! so by your logic a jump from GPU to 1Thash is the same. i think you failed maths at school sorry but you deserve that

The last freshly minted Bitcoin won't be anywhere near 2040.  I believe ~2040 is when the subsidy drops below a full coin per block.  "2140" is the date where the subsidy actually becomes 0 because it would be a fraction of a satoshi.  The difficulty adjustment keeps the halving events *roughly* 4 years apart.  Obviously early on in the life of Bitcoin these events will happen more frequently because difficulty adjustments are a backwards-looking adjustment rather than forward-looking adjustment.  Exponential growth is not sustainable, and the previous posters were correct.  GPU -> ASIC is basically the same as CPU -> GPU was.  Actually, what we're seeing today isn't even close to the jumps we saw from CPU->GPU in terms of percentage growth when GPU mining first started.

The first time GPU mining was introduced is the first and only time in Bitcoin's history where the limit on a difficulty increase (+300% in a single adjustment) was ever hit.

not sure thats correct?

I'm gonna attempt to break the spell again...

...5:38:06 and counting.

Your first problem is using eBay to buy a bitcoin miner. The second is I have no clue what you're arguing, that bitcoin is going to die due to asic, that asic is 'cheating', or that the growth curve right now looks any different from the one 3 years ago where using gpus was discovered

Or the crazy time just after MTGOX opened where the network difficulty increased tenfold during July 2010.
