Side-chains are far fro "solutions". It needs more development to call it as a solution.


Are you spamming? Its not a problem to oppose XT but don't spread FUD or disinformation. If you have valid proofs, post it.

Why store coins in a web wallet when you have better wallets? Install a local wallet [1] or buy a hardware wallet [2].

GreenAddress.it wallet is an online wallet. If you are looking for a lightweight desktop wallet, you should go for Multibit HD or Electrum.

It is one of the best online wallet. In fact, I don't think there is any other wallet which is as secure as this. But, recently, some people have claimed that there are some problems. I highly recommend you to first test with small amount and if it is working properly, use it. Don't forget to save the locked transaction. It is needed to recover your funds if their site is down.

If you have just searched "GreenAddress bitcointalk", their official announcement thread comes. https://bitcointalk.org/index.php?topic=521988.0

Almost all pools don't do this because they will loose their block rewards. So there is an incentive for miners to not to do this which will prevent >50% attack. Besides, miners moves their hash power to another pool if this happens like they did when Ghash.io had nearly 50% of total hash power. This is not a big concern unless if more pools start closing down.

Which version are you using?


You only need to open Armory for syncing when Bitcoin Core is run as a background process to download blockchain. You don't need to run Bitcoin Core manually for downloading blocks. That is why, I am asking "why you need to run Bitcoin Core and Armory simultaneously?" Why don't you run Armory alone?

Why do you want to run Bitcoin Core and Armory simultaneously? Is not Armory enough?

Usually, Armory runs Bitcoin Core in background. I think if you uncheck that option, you may not get any problem.

Watch-only wallets does not contain any private key. If you did not save private keys, your Bitcoins, if any, are gone.

Edit: It's look like above two were faster.

Which all commands are not working? Didn't you follow those commands in the same order? Changing order may cause problem because of unmet dependencies. I maybe able to help you with this via TeamViewer or similar but more secure software. For this, you will have to trust me because you are giving access to your computer to an unknown person(me).

Double-spending transactions won't work because transaction included in the blocks in question are invalid blocks and will be rejected in Bitcoin Core 0.10.x or 0.9.5 and Bitcoin Core <0.10.x switches to longer chain(main chain) which will also make those blocks useless. So the transaction you got earlier won't be there when those blocks are rejected. That's why, you should wait for ~30 confirmations or near to it for making sure the transaction you received is included in longer chain(main chain).


No, its not. Like in the above case, if your transaction is included in invalid block but not in valid block, your Bitcoins returns to your address when that chain or block is rejected. You will have to make sure your transaction gets enough confirmation.


In other words, wait for more confirmations than usual.

Can't you copy-paste those commands in terminal and click enter/return? Hope errors are not there.

Which version of OS X are you using?

There is no amount left to use as transaction fee and hence, the fee is 0.00001004BTC. Wait, that is what is best to do now. Next time onwards, check transaction fee before you send.
