These "people that invested too much in Application Specific Integrated Circuits for Sha-256" will have the biggest part of hashrate. They simply don't let change the algorithm.

That isn't really something miners can dictate.

You ask for miner vote in hard forks because you want them to back the fork up with their hash-rate. It is essential for the security of the fork, though it's not essential for switch to happen, it's completely up to the users (merchants, exchanges, etc. included). If miners don't switch, the new fork will be less secure, so there is some influence there.

However, even that doesn't apply for the ASIC situation because you can't make use of that hashrate anyway.

Besides, an algorithm switch would very likely be planned a few years in advance. There will be plenty of time for old hardware to become obsoleted, which is inevitable anyway with advances in ASIC development, even without a protocol change.

Mi bedaŭras memvola, sed vole aŭ nevole ministoj havas la povon ;-)

It the miners with the highest part of HR don't switch, the blockchain will fork, with the SHA256 blocks as the main ones, and the others simply orphaned.

Proposals for improving bitcoin are like asses: everybody has one

NO.
Its upto each client installation to decide what block they will use and validate. If bitcoin issues a new client with new algo going forward, the fork used by most users (especially exchanges and traders) would be the prevailing one.

Update

This is a picture showing the relative size to the laptop. One with heatsink and one without.


We also tested it on the USB-hub. Seven in a row run over a whole night and are all very stable.

wait - so, if they'll run without the heatsinks, why did you make/order heatsinks that we now have to pay for?

The heatsink costs $0.1 or so and mitigates the temperature from the hashing IC. The IC works fine on high temperature but it may hurt the fingers if accidentally touched at its back.

They look great! And what a cool way to introduce friends to bitcoin by letting them participate in mining. That's what hooked me in the first place.

I'll buy a bunch of these if/when the price comes down to 400-500 mbtc.

Yeah man, 10 of these USB is 20BTC or $2.4K at current exchange rate. A bargain indeed.

This could make sense as a present, or as a funny toy... I really love the gadget itself. But come on, running ten of them, knowing they will never ROI... Why? What's the purpose?

Yes I hold stock and will also be buying these. why buy GPUs when we can get this? Also I do not have much trust in BFL.

well nobody is buying GPU to mine bitcoin as it is not economical these days. The same thing applies to this - does not matter that it's more efficient, or that there is currently no better competition shipping,  you will still not see a return; and if ultimately you are losing money- where is the sense?

When this was announced, there was a huge amount of interest, everyone and their dog wanted one.. at this price, much smaller percentage are willing to be milked

Have them mine while we find the right price...

I'm tired of hearing about this,
I call for a no reserve auction NOW !!!

I'm just saying that I think it's pointless to have 10 of these guys mining because of their price per MH/s. I think we all agree that these are not intended to be a mining investment, but a cool toy - I think even friedcat agrees on that by how he presented the product in the OP. Thus, I can understand buying some of these as a curiosity, as a gift, etc. etc. etc... But to run them in a "semi-pro" way in a big USB hub is pointless IMHO, who is really going to do that? Frankly: are you?

as far as i see, there is no intention from sellers to lower price ... so i guess everybody who say ill buy 10 when price will get lower should rethink their plans Smiley

The plan is to wait until competing products drive the price down. It will happen eventually.
