When an unconfirmed transaction gets dropped from the mempool, all transactions that used the unconfirmed transaction as input will be removed also. This means your friend's transaction (and any transactions that used it as input) will be dropped along with your transaction

If you would prefer the transaction to be confirmed instead no matter how long it will take, you can push the transaction back to the mempool every time it gets dropped. To push a transaction, simply go to the sites listed here and enter your raw transaction. You can get the raw transaction from bc.i by adding "?format=hex" at the end of the transaction link like this. Make sure you save it (and your friend's raw tx) because it won't be available once bc.i drops the tx

Sorry. I mean that it will might stay unconfirmed for days and gets dropped from the mempool. The bitcoins will be returned to the sender's wallet and they can send another transaction with higher fee
The time it takes for most nodes to drop your transaction is 48-72 hours provided that no one rebroadcasts the transaction every now and then

Edit: Corrections.

No. It just can't verify signed messages with line break. But a lot of people love to use them for whatever reason

Yes it is. But it probably won't happen right after the halving. I think it will take time for the market to adjust with the current price and feel the effects of the halving. Right now there's a lot of happy people who are more than willing to lock their profit once the price reach $1000

It might take days instead of hours. No one can guarantee how long a transaction will take to get a confirmation but your transaction fee of approximately 1.8 satoshi per byte is very, very, low compared to the recommended fee of 40-60 satoshi per byte. I've seen transactions with double your fee not getting confirmed at all

Can you give us an address? Just read the ETH/DAO and poloniex news so I'm kinda blind on this

@Xinzark
What makes you sure that OP didn't create this thread just to frame traderbit? Anyone can do that

I'm sure you have some relatives/friends/acquaintance and/or some other way to get loan like medical loan from your bank. Instead of asking some random strangers that most likely won't give you a cent, ask them instead

Look around this section. No one would even give 0.001 to a newbie with 2 posts. You'll need collateral. Personal information means nothing unless the lender lives near you and is willing to risk not getting repaid on-time

Am I the only one who believe that HD wallet is not all that good for privacy? Someone get your master public key and they'll be able to see all your transaction. Or did I misunderstood that?

For google authenticator. it's here => https://support.google.com/accounts/answer/185834?hl=en#phone

This, might be useful.

I've said this a lot of times: stop using blockchain.info. There have been at least 2 cases of this that I know of. I'm not 100% sure what caused it but people lost money and blockchain.info can't seem to do anything to fix it.

Here's the previous cases I mentioned:

Growing old, weak, and senile

Escrowed trades are very much different from no collateral loans.

You should know that you might get a negative feedback by asking for a loan without providing any valid collateral while you're still newbie. No one here trusts this kind of loan

If I'm gone in the near future, that's on you, Gleb

That's satoshi's pic. A completely different person. Why'd you think this is in off-topic? 

Yes. I have a separate cold storage just for hodling which I plan not to touch for a long time. At the very least not before the 4th halving
All other crypto are just for quick profit (mainly because there's nothing better at the moment)

I'm quoting this for prosperity.
