Man, this stuff gets technical fast.  What;s to stop opponents of this medium of exchange from mining it into value-less-ness with a high frequency trading set up?

They'll need to have a lot more processing power than the entire legit bitcoin network I believe in order to mine enough coins to trade at high frequency and high enough volume to make a difference. And given that we might have the largest hashing capacity network in existence, that would take a fair bit of cash and hardware, which might drive the cost of hardware cheaper for legit miners and so make it even harder for them to crash it.

if the price of bitcoins keep falling like it has been, its going to be a loss for some miners.  if the price starts to creep back up near the $20usd/btc then it might be worth it.  just mine and hold.... and hope the price goes back up to $30 or more if you want to see a ROI.

Given the time and electricity cost, only those very high end card can generate a profit

well its kinda true i was working with hd5850 not so good,

not rly to be fair, you can build a decent rig with multiple 5770 cards,
you can stack up to 5 on a simple 700w psu,
given that your mobo can accomodate them ofc, (3 regular slots + 2 on pci-e x1 risers is standard, i think)
So you have a 1ghash mining rig with a relatively cheap psu (2x5830+5850 would require at least 850w to run properly OC'ed)

Last time i checked, 5770 was one of the best at $/Mhash and W/Mhash
And it is as low-end as it gets.

According to the chart here: https://en.bitcoin.it/wiki/Mining_hardware_comparison

It's still behind a 5830 and 5850 for $/Mhash

Another problem is the rising difficulty each month, soon it will be only 0.1 BTC even on a machine with 1Ghash power, unless BTC rise in value quickly, I don't see a bright future

Anyway this is fun, I just bought a second hand 5870 which now runs 400Mh/s and testing
