There is nothing electrum can do about it. Here is what you should do.

1) Ask you seller to give you the transaction id. See on any blockchain explorer that indeed your seller has sent in your transaction.
2) Check if windows firewall or any other antivirus or firewall is not blocking your traffic to electrum.
3) As HCP said, see if you see the green dot at the bottom right corner of electrum.
4) Report back here and let us know what the issue was.

Well for me personally, I prefer an offline PC to generate new Seeds. For keeping the seed save, I prefer atleast 3 copies, 1 on an offline PC, 1 on a usb Drive and 1 on a plastic covered paper. I have never thought of splitting up the seed but it sounds like a good idea. As for keeping encrypted seeds on cloud storage, I am always against that. You never know when your data might get leaked and with the dictionaries out there these days, its not the risk i am willing to take. Last question is a bit tricky, The ideal situation will be to have multiple storage points but they do carry a risk. A home safe sounds like a good idea as for banks, its a big no! Parents house yes! I believe there is no perfect way to protect your btcs, you can just take necessary steps to prevent your losses.

Well i believe Bitcoin was never intended to be a zero fee currency. As far as i know, bitcoin transactions were called almost "Free" because of low fees, But i would like to know the technical side of aspect for this 0 fee not getting pushed. In theory we should be able to broadcast it. From which websites have you tried to push this transaction? Try a few of them and see if you get any success.

Lol, you are looking for a pirated script, seriously? This will only end in a disaster. Even if you find a 'good' script, from where will you fund it? How will you do its promotion? If you can't spend money on a custom script, then i don't see how will you sustain the website in the long run. If you are serious about this project, spend some money on the website and build something unique. Goodluck!

Your only option is to wait for a response, but if you feel like you are being scammed, you should open a Scam accusation here on the forum it will alert many users over here, BTW personally i am hearing about coin jar for the first time, So i can't comment about them whether they are legit or a scam.

Edit: did you verify your account with them? Maybe they require your verification before they can process your payout.

This is the exact reason why need further encryption, I am trying to build an open source wallet which will use your fingerprint to encrypt the wallet.dat file, along with password and 2FA encryption, that will be one of the solutions. Other than that your current best option is to get a windows copy from microsoft and do a brand new offline installation of windows and never connect that pc to internet, That's the safest you can go. Also Don't use ISO files from the internet, they can be modified quiet easily.

As far as i know the wallets don't work that way, each wallet software creates the wallet.dat file differently, you can't import a bitcoin core wallet to electrum and vice versa. So your only option is to check the address which had your 12 BTC's or just be calm and wait out the sync time.

I think your Bitcoins are lost, as you are saying that you encrypted your wallet after downloading it, The encryption won't magically apply on the hackers wallet file, Do you have the address on which you had 12 BTC? It's the only way to see if your bitcoins are there or not. If you don't have the address on which you received the BTCs then your only option is to wait out and let the sync complete. Also it is your fault for storing an un-encrypted version on dropbox. Never upload your wallet files online. SMDH!

Well if you are serious about learning programming, then i will recommend you to learn python. It is one of the most used languages and it has quiet a demand in the cryptosphere. You can take different courses on python from websites like EDX and coursera. I will recommend you take this course https://www.coursera.org/specializations/python it will help you alot and get you into the programming world.

Are you looking for a web developer? I can only do IOS and Android. PM me for more details if you want an Android and IOS version of the casino. Also What kind of budget do you have for this project? Just aheads up, expect upwards of $1000 for each platform.

I totally agree with krishnapramod, you don't want to use adsense with bitcoin related faucets or games. However rewarding apps do use adsense and offerwalls to get their income from, i don't know why adsense has a dual policy for bitcoins. I have seen tons of rewarding apps use adsense and they never get banned. But for faucets you get a straight ban. Try different networks like adsterra, they are faucet friendly.

As for an idea here is one, make a competition game, and reward the user with most wins or points a pot amount.

Well you can use finger print as an additional security layer, just like 2FA I didn't say it has to be just finger print or face lock.

---

I am planning to make it open source, so you don't have to worry about app getting the fingerprint data, on new devices the fingerprint readers are quick and work almost 99% of the time, As for laptop's one may buy a quality fingerprint reader.

Would really appreciate if you can send it to 'Thekool1s' on pastecoin. Thanks

Your post is so confusing. Let me get some things cleared out first, You created a 2FA wallet with a new seed on 2 sept. You received some btc's on an address generated from that seed, Then you tried to spend some btcs but it failed because of 2FA sync time issue, So you decided to restore your wallet with the seed and when you restored, your btc's didnot appear? You thought that it was a sync issue so you sent some btc's to another address generated by the same seed and they appeared. You only see your earlier BTCs if you open the wallet file that you have on the usb drive. You see your new coins and old coins seperate on 2 different wallet files, This means that your usb wallet has a different seed and your new wallet has another seed. What you should do is load up the usb wallet and see its seed and compare it with the seed you have written down. I am sure that both wallets are using different seeds.

yeah i have looked around and found about case wallets, but they are sold out as you said. But i am looking for my laptop(that's what i meant by PC). It has a fingerprint reader on it, I agree the userbase is small but it can be a game changer, same thing can be applied for face lock. I will look in to it and try to make one in my free time.

Hey guys, i want to ask if there is any wallet software which encrypts the wallet.dat file with our fingerprint data, so that instead of typing a password which can be compromised by a keylogger, that wallet software should use our fingerprint data and some how use that data to encrypt the wallet.dat file and it should ask for the fingerprint to send btcs etc. Do let me know if any wallet like this exists or not. If it doesn't i will try to make one.

Your information is partial, i have a few questions, I have a friend who is good in python, he can probably do this, From where do you want to get the news from? And what kind of alerts do you want? A Notification on mobile phone or an Email/sms notification..

Yes, most wallets give you a warning when you are trying to spend unconfirmed coins, so may be the coins your 'local exchange' sent you haven't confirmed, that's why may be you are receiving that email notification. Ask your local exchange to give you the transaction id and see if they have indeed sent the payment in and do check whether the transaction has received any confirmations on it.

It isn't rocket science, just simple maths, you tell them hash rate, the cost of electricity, the investment cost, coin you want to mine and they simply calculate on what hashrate you can mine a solo block and then divide that with the X hash you have. You get the amount of coins you will mine daily from that, Remember this will fluctuate on daily basis you that X amount of btc daily to is an approximation. After that its simple math, daily amount generated in dollars - daily cost and you get your figures.

you can send your btc address to mocacinno if you want, but i will recommend you to check it yourself from other blockchain explorers, you will find plenty of them by doing a quick google search. Are you sure your exchange has processed the payment? Or did they only sent you a notification email that you are trying to send X amount of BTC to XYZ address? Also how trusted is this your local exchange? May be they have scammed you by not sending your bitcoins at all.
