"The idea of "bitcoin days destroyed" came about because it was realised that total transaction volume per day might be an inappropriate measure of the level of economic activity in Bitcoin. After all, someone could be sending the same money back and forth between their own addresses repeatedly. If you sent the same 50 btc back and forth 20 times, it would look like 1000 btc worth of activity, while in fact it represents almost nothing in terms of real transaction volume.

With "bitcoin days destroyed", the idea is instead to give more weight to coins which haven't been spent in a while. To do this, you multiply the amount of each transaction by the number of days since those coins were last spent. So, 1 bitcoin that hasn't been spent in 100 days (1 bitcoin * 100 days) counts as much as 100 bitcoins that were just spent yesterday (100 bitcoins * 1 day). Because you can think of these "bitcoin days" as building up over time until a transaction actually occurs, the actual measure is called "bitcoin days destroyed". This is believed to give a better indication of how much real economic activity is occurring on the bitcoin network.

So how well does it work? Well, it's still not perfect, because the other day I moved some coins out of a wallet they've been in for several months without spending them or giving them away. And some genuine businesses have very rapid turnover in bitcoins, so they're not being measured well by this method. But it does do a good job of filtering out the "noise" of bitcoins that are just "bouncing around" without really going anywhere. The graph of overall bitcoin days destroyed is believed to show that the genuine level of activity in the Bitcoin economy is continually increasing--it's not just one person experimenting by rapidly sending the same coins back and forth, flooding the network with meaningless chatter. Looks pretty good, hey? "

no if u read the threads its cause abodi been spamming abuse complaints to the hosts. doesnt help us much because now we cant see our accounts.

not really. i dont see anything special about them anyway, too many rules

i saw a login screen for Gemini exchange but when i clicked the signup button it refreshed and showed me the old 'early access' screen. did anyone else see that? i keep refreshing but cant get it to show up again

okay so the bears just admitted they dont actually hate bitcoin but just want to short it.....
if they really hated bitcoin they wouldnt be, you know, placing trades with it?

its like if i didn't like oranges and sat around talking in an orange forum all day. i dont get it?

he said he delete the old formula post right after, jan 2014 is near beginning of service. the quote is from old time and has nothing to do with insurance dinkerplinker

the refunds and dust payments are fake, he paid them during hard fork so he unspent it
so there has been refunded 0 bitcoins so far
