Re: Bitcoin services under attack?

all bitcoin transactions are recorded in the blockchain, if you sent it on its way then it irrelevant if their client died or not
look your transaction up on http://blockexplorer.com/

It's not irrelevant if you've emailed them about it and received no response from them in 10+ days.

I accidentally duped a 10 BTC transaction to a merchant using mybitcoin.com and am yet to get any response from them (mybitcoin.com, not the merchant).

Don't use MyBitcoin? The whole strength of Bitcoin is that it is 100% decentralized; why give that up?

Do you mean boycott all merchants that use mybitcoin.com to accept payments?

That will drastically reduce the take-up rate for new bitcoin merchants.

Not every store owner knows how to set up a wallet on their own server.
