When reports of this email scam first started appearing last September the perpetrators were discovered to be using a Matbea wallet. That appears to have changed. On May 30 every output transaction from hundreds of reported blackmail scam addresses went to a Poloniex wallet address.

The total amount of bitcoin in circulation decreased by almost 9 in 2017 due to “burn” addresses. Burn addresses, like the Genesis Block, are deadlier than “zombie” addresses, because there is no chance of coming back once BTC is sent to it. There are almost 400 known bitcoin burn addresses, i.e. valid addresses with no private key, to which, for a variety of reasons, people have sent 2,759.42507135 over the years. In 2017, 9 of these addresses received 8.97140133 BTC. That is way down from 2016 when 26.04 BTC was burned. Continue reading 8.97 Bitcoins Burned In 2017→

There will eventually be 21 million bitcoins mined however that will never be the true number in circulation. The distinction is important if you want to precisely measure bitcoin value and market capitalization which is setting new records. Not all bitcoin addresses can be spent. The genesis block can never be spent. Likewise any bitcoin sent to a “burn” address are also forever unspendable. A bitcoin burn address is like an impossible vanity address. There is no private key to a burn address and one would be impossible to generate. These are not merely ‘zombies‘ but truly gone forever. How many bitcoins have been “burned” exactly?
