I have gotten the problem before and I have found the following steps to help. First, update electrum to the latest version. Next, try manually selecting a server and try out several of the server. Sometimes you just need to wait a min or two if you haven't opened in a long time.

The current version of Electrum (2.9.3) does not support segwit yet. However, according to the developers, the next version of Electrum should support it.

When you send a transaction, the input has to equal the output plus the fees. That means you have to send the entire 0.0279. The 125XE6W8SX6vK569jGFCNahMWakqiSb4uG is probably a change address that you own.
You choose to not use change addresses by going to Tool => Electrum Preferences => Transactions and then uncheck change addresses and the extra 0.01 btc will be sent back to your original address.

I'm not an experienced trader, but I have an interesting theory.
I think for trading and other +EV games (poker, sports betting, etc), you should be trying to get the highest median income. What I mean by median income is, assuming the odds of the trade are known, the 50% percentile outcome if the same trade was executed infinity times.
Ex: you spotted a possible trade with 50% to 2.02x your money and 50% to lose all your money (EV +1%).
If you execute that trade infinite times with 50% of your bankroll, you lose 24.5% for every 2 trades. Calculations: (.5*2.02+0.5)*(0.5)=.755
However, if you trade 0.1% of your bankroll, your profit would be too small. (0.001*2.02+.999)*(.999)=1.00001898
The ideal trade amount is 1% of your bankroll (double check that, I might be wrong). (0.01*2.02+.99)*(.99)=1.000098
In fact, unless your profit margin is very wide, you should only be trading a small amount of your bankroll (<5%) per coin. Trading with 100% of your money is more or less gambling maybe with no house edge (if your good at trading).

Firstly, bitcoin transaction fees are really high right now (the average fee is $7) so if you set the fee too low, the transaction might get stuck. https://bitcoinfees.21.co/Anyways, if you can create your transaction manually by going to https://www.coinb.in/#newTransactionFirst, load the address from which you are going to send the coins. Then, enter the outputs. One of the outputs can be your own address. The difference between the inputs and the outputs are the fees. After you submitted the transaction, go to electrum's console (view => show console) and put in this code: signtransaction("rawtransactiongoeshere")Finally, copy the numbers after the "hex" and put it in this code: broadcast("hexcodegoeshere")Please not. that you might have to set a password to your wallet for this function to work. At least I haven't gotten certain functions to work without setting a password. https://bitcointalk.org/index.php?topic=2100858.0 |

Unless the attacker has over 50% of the hash power, there is no reason for him to not broadcast the block since his block chain is just going to be overtaken by the rest of miners.
Not needed. All you need is a node with an extremely good connection to many network peers. When you find a block, you hold it and keep it to yourself. Next, when someone mines a block, your very well connected node will be one of the first to hear about it and you can broadcast your own block instead. If your block somehow gets propagated faster than the other pools (ie. Being directly connected to large mining pools), they will build on top of yours. If another block is found on top of yours, you don't lose anything. That's a very interesting concept. But that strategy is very risky though. If the someone else broadcast his block and you aren't one of the first to hear about it, you could very well lose your block. I don't think that the big mining pools wouldn't be well connected. Also, you are wasting your hash power by not broadcasting and immediately mining the next block. |

1)Is there a set fee for sweeping or is there a way to find out how much the fee would be to sweep? I know you can adjust the transaction fees, but that did not seem to do anything for sweeping.
There is no set fee. You can choose your fee. 2)12.7kb is large, looking up average current fee is 450 satoshis/byte using that it would be about .057BTC ~ $240 fee to sweep in a little over 1BTC. Is there a better route to get the coins out of multibit and into the trezor?
You can set the fee to about 200 satoshis/byte, and the transaction would go through in about a day. Also, consider getting rid of the inputs that contain dust amounts of btc to reduce the transaction size. 3)My balance on my Multibit classic is just over 1.04BTC when sweeping the keys it says amount received is 999.9 mBTC. Is that how much would show up in electrum after the fees or do I need to check for unconfirmed transfers? which the last transfer was in 2014.
Can you give us the transaction? |

I can assist you with the Chinese translation since I know both Chinese and English fluently. Although my portfolio is small, I am trying to expand it. https://bitcointalk.org/index.php?topic=2114825.msg21147367#msg21147367Since I am relatively new to translation, I am willing to accept your best offer (basically I'll do the translation and you can tip me whatever you want). |

The reason your transaction isn't being confirmed is because the transaction fees recently have gotten very high. There are many unconfirmed transaction in the pool. Eventually, the transaction will go through if you give it some time (like several hours).

10 secs is a bit too short for the block time since the blocks take a few seconds to propagate. Although, a shorter block time would be advantageous as it increases the maximum transaction size and reduces transaction fee. However, I doubt that any sort of change will happen to bitcoin any time soon (except for maybe segwit2x) since no one can ever agree on anything.

There is a crypto-currency called tether. Tether is always worth exactly $1 and uses the blockchain technology similar to other crypto-currencies. Its becoming more and more popular in the last few months. https://tether.to/ |

Does the dividends update automatically? Would be nice if dividends and splits are calculated automatically. Feel like there is a delay when between typing in security and the security showing up. Otherwise, it would be a neat tool to do practice trades.

When you are using Electrum, you using their servers, but you are still storing your private keys on your own computer. Unless you downloaded a fake copy, only you would have control of your keys.
If Electrum tried to change their software to steal bitcoins, people would start noticing as the code is open source. If Electrum tried to give false information from their servers, you would still retain your bitcoins (even if the display isn't correct), and can simply export the private keys to another client.

Not read anything about the BCC as of yet, if you have any ilnks/info you can share that would be cool!
On August 1, bitcoin was forked, and the new currency was called bitcoin cash. Everyone who had bitcoins before the fork now has the same amount if bitcoin cash as the amount of bitcoins they had. (If i had 0.01 btc before the fork, I would get 0.01 bcc). The BCC are on the same addresses as the btc. Claiming your BCC is a bit complicated, but you basically create a new wallet for the btc and export the privates key of the original btc wallet to BCC wallet. https://bitcointalk.org/index.php?topic=2054046.0 |
