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 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

The First Ever Bitcoin Donation Address League Table

Gavin Andresen’s Faucet Ranks #1 With 19,922 BTC Received

One of the most redeeming qualities of the bitcoin community is their generosity. For every scammer trying to take advantage of the blockchain’s anonymity, there are multiple others giving transparently to a cause in which they believe. From the original Wikileaks campaign, which arguably put bitcoin on the map, to the current Free Ross movement, there is no shortage of organization’s taking advantage of bitcoin’s frictionless ability to cross borders and replace traditional payment systems.

This first ever ranking of bitcoin donation addresses is easily led by Gavin Andresen’s original faucet addresses. This faucet originally gave away 5 BTC just for solving a captcha when it first went live in July 2010. Talk about generous! The total received balance on these addresses is almost three times that of the second ranked Bitcointalk Forum address.

The popular Free Ross Ulbricht campaign address currently ranks #12. Free Snowden ranks #25.

Here are the rest of the top 50 bitcoin donation addresses based on total received balance out of 475 reviewed. Continue reading Top 50 Bitcoin Donation Address Rankings
