I think 65.000
BTC is just example in this case, but if you have lots of bitcoin and you want to "destroy" it, just send those to many addresses and delete the wallet
Not sure on that one but:
1CounterpartyXXXXXXXXXXXXXXXUWLpVr
Should be a safe burn address. Looks like 2000+ BTC have been destroyed there.
Is it similar with 1BitcoinEater?
As long as there is not private key possibility generated with the public key, the amount in the address is considered "burnt".
Like:
1BitcoinEaterAddressDontSendf59kuE
But it will be better to send them to charity:
Sean's Outpost: 1M72Sfpbz1BPpXFHz9m3CdqATR44Jvaydd
Wikileaks: 1HB5XMLmzFVj8ALj6mfBsbifRoD4miY36v
etc etc....
Really, why to burn bitcoins when you have possibility to donate it and help people who really need it? On one adress posted above, 21 million usd bitcoin was burnt and seems most people sent some cents maybe to be indexed in transactions of that adress, why? When you can really do charity.
See this thread, this man really does amazing job with bitcoin, don't waste it, send him:
