What's happening with the network?

[Mickeyb]

I have sent 2 transaction, 1 with 0.00001 tx fee and 1 with the 0.00002 tx fee. Both unconfirmed for over several hours. What a heck?

Yes I know, but how long will this last?

Nobody can be for sure. Either until the attackers stop doing what they are or until we have bigger blocks (who knows when). It's obviously a problem that the core devs have failed to see.
A lot of people have been complaining, however investors do not care. You can see a positive trend when it comes to the price.

I would suggest that people stop being cheap and include big fees so that their transactions process sooner. Recently I've included fees that add up almost to a dollar, and thus had no problem.
This is only temporary and I don't see including a higher fee at the moment being a problem.

You need to be more generous with the miner's fee if you want fast confirmations, yesterday got some transactions confirmed in next block fee 0.001 and 0.0003 both transactions of 1 bitcoin, one gad a lot of inputs so I was a bit more generous.

I am sending from mycelium where I really have only 3 options, otherwise I would be more generous.
Another thing, my sent BTC keeps coming back to my wallet even though in blockchain.info it sits as an unconfirmed transaction. What's this all about?

OP, you're too cheap on fees. 1000 satoshis is 'economic' fee, and even without 200MB of spam, would take several hours to confirm. Next time, check this site https://bitcoinfees.github.io/, or http://bitcoinexchangerate.org/fees, and decide how fast transaction you want. Fees there are calculated per KB, a transaction of 1 input 2 outputs take about 250 bytes.

On Mycelium, use normal (0.0001) or generous (0.0002) fee. For standard transaction that is 40 or 80 satoshis per byte. Will beat spammers, they are using 1 to 5 satoshis per byte.

Every node has its own pool of unconfirmed transactions. Once sent, you can't delete your transactions from other node's mempool. Your wallet calculated that transaction takes too long to confirm, and now allows you to use these same coins again in a new transaction (double spending). If some miner in the meantime confirms your previous transaction, your coins will be gone from your wallet.

My bad, I've sent two above transactions with 0.0001 and 0.0002 tx fees, not 0.00001 and 0.00002 as I've written.

I would have sent even with 0.0005, I don't care, but mycelium won't let me, or is there a way that I don't know to set?

Thanks for the explanation!

Also can I cancel my unconfirmed transaction somehow?
Thanks

No. Once sent, you have no control on that transaction. It's like sending cash - you can't cancel while in delivery.
Have to wait for confirmation, or double spend it if your wallet allows that, with higher fee. And in mycelium you can't set it higher than 0.0002.

You can rebroadcast your stuck transaction, to speed up the propagation on the network, maybe will get to some miner faster. First go to blockchain.info and find your transaction ID, then add to the end on the address bar: 

?format=hex

(like https://blockchain.info/tx/8d3950c9db935a0a91fb075a1fcc3b627f28daf1f35252cb3ec9b8459070a0dc?format=hex)

then copy hex string to https://coinb.in/#broadcast and submit.

Can I double spend in mycelium?
Sorry fod bothering you and thanks for the help.

Can I double spend in mycelium?

Don't know. Never tried in mycelium. I think not. Only when the wallet drops waiting for tx to confirm and shows your balance back.

Few more links to rebroadcast (push) raw transaction:

And how long does this take with mycelium?
