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 “zomby” 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.

Total Blocks: 336,860
Total Transactions: 55,479,774
Total Inputs: 137,314,100
Total Outputs: 152,906,795
Found 58,951,529 addresses which have ever been used.

Thank you for any help or suggestions.
