    Here is something that only happens to a newbe like me.

    I sent BTC from Coinbase (using their e-mail method) to Cryptsy. The money left CoinBase (as my balance shows) and never made it to Cryptsy.

    Apparently I sent it to the wrong address (from my account on Cryptsy) that was designed for internal transfers only in Cryptsy. My question is: can one assume that at some point the final amount of currency will drop since people will be losing coins to black holes like I did? Is that accounted for in the crypto coin system? So far I am not getting and responses from CoinBase about their ability to re-claim that coin. Any ideas if one can do that on his/her own?

      Also its not going to involve coinbase any more. BTC is a one way train ride my friend.

    Alon, Typically, removing coins from the money supply means a tightening and a rise in value of the remaining coins. However, I'm guessing that not much will disappear into Black Holes; in fact, none, it's just that someone -- not the intended recipient -- has your money. And I think you will find that unwinding transactions is not built into the BitCoin protocol. Hey, this stuff does happen from time to time. Best regards, Shep

      What disappears into black holes is any coin stored in addresses with lost private keys -- gone forever but the btc markets will never know.

    Would like to explore how best to incorporate an identity tracker within Bitcoin in order to validate the parties (without use of PII).
