Lost Forever 26.04 BTC Burned In 2016

Lost coins only make everyone else’s coins worth slightly more. Think of it as a donation to everyone.

– Satoshi Nakamoto

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?

The Mt. Gox bankruptcy trustee recently announced they would not be releasing the complete list of bitcoin addresses controlled by the exchange.

From cryptocoinsnews.com

Citing security concerns with the possibility of endangering personal information and the privacy of users in relation to the planned release of the list of bitcoin addresses controlled by now-defunct Bitcoin exchange Mt. Gox, the trustee has suspended the release.

Fortunately we have collected some from other sources and will update as able.

belongs to Satoshi Nakamoto. There were 14 blocks mined that day, the first day of bitcoin mining.

The Ever Popular DeepBit Mining Pool Address

Old DeepBit.net mining pool home
The bitcoin address of long defunct mining pool DeepBit [1VayNert3x1KzbpzMGt2qdqrAThiRovi8] is still somehow crazy popular. According to Blockchain.info’s “Popular Addresses” page, DeepBit holds the #8 overall ranking for most frequently used bitcoin address. But how can a defunct mining pool, that hasn’t found a block since 2013, and has only 47 transactions since January 1, 2015, still hold the #8 overall popularity ranking based on # transactions?

The most likely explanation has to do with the significance of DeepBit in the early days of bitcoin history. Continue reading The Ever Popular DeepBit Mining Pool Address
