USDT is a omni token, which is built on top of the Bitcoin blockchain. That's why you can send BTC to your USDT deposit address at Bittrex.

Only Bittrex can recover your coins. That's a fact. If they don't want to help you, then you unfortunately lost your coins.

Not sure if this would work, but it's worth the try.

1. Import your Ledger Nano S in Electrum;
2. Select the "Addresses" tab; (if it's not showing: View -> Show Addresses)
3. Right click the address you want to spend the coins and choose "Spend from";

Please report here if it worked.

I suggest you to register an account at AltPocket.io; It's a portfolio that automatically pulls all your trades from some exchanges (including Bittrex) and shows your open investments.

E.g: If you buy 1 LTC for 0.0105 BTC, your profile at AltPocket will show an open LTC investment.

If the Litecoin price goes to 0.012 BTC, the portfolio will show that your investment made you a profit of 0.0015 BTC.
or if the price goes down to 0.009 BTC, the portfolio will show that your investment made you lose 0.0015 BTC.

When you close your investment by selling your 1 LTC, your profile will show your overall profit, net worth, and old investments.

Changelly only has crappy rates when you want to exchange USD to BTC - most likely because you pay with Credit Card. Right now, if you want to buy 1 BTC you need to pay $6535, which is $1000 over the market price. AFAIK, the Crypto <-> Crypto exchange is sometimes even better than the one from ShapeShift (they also have a higher maximum per transaction);

It really depends on you to check both websites for the best price before making a transaction.

The website is probably earning less than their ads, while their users see an increase in their CPU usage, making them stop visiting the website. Plus, if you want to do that with your website, at least write a warning or let users choose if they want to contribute, instead of hiding that from the regular user.

I don't mind ThePirateBay do that, for example. Meanwhile, there are websites that are pure garbage and are starting to use ads + web miners to milk their users - which don't deserve anything from me.

---

From the source posted by krishnapramod above: the majority of websites using web miners belong to the TV/Movies category. Imagine a user that don't know anything about cryptocurrencies, start marathoning his tv show for more than 4 hours, without knowing that his CPU is being used to mine Monero... That's just shady.

Btw, If you are going to buy with Coinbase, use GDAX (which is Coinbase's exchange) instead of the user-friendly buy form from your account; You will probably save a ton of money in fees. Making it even cheaper to buy your coins. Check this video[1] for more information.

Do you have your wallet seed? If so, you can disable 2FA.

In Electrum, create a new wallet with "File" -> "New/Restore" -> Select "Standard Wallet" or "Wallet with two-factor authentication" -> "I already have a seed" -> Paste your seed -> Select "Disable";

This version is current only running in the Bitcoin testnet chain. I would wait until they release a working version for the regular user that is probably going to come with a video or guide.

Are you looking for a safe and private VPN and email provider? Check privacytools.io[1] for unbiased reviews about VPN's and Email's.
I myself would use ProtonMail (can be used for free or extra features that can be paid with Bitcoin) and NordVPN (has a free 3 days trial);

One of the reasons could easily be the S2X fork that is happening next month. People want their free "airdrop" just like what happened to Bitcoin Cash, so they are selling all their altcoins for Bitcoin. Just check all the other cryptocurrencies and you will see how the recent Bitcoin rise is correlated with the price drop on all other altcoins.

We may even see another rise if S2X dies in a few months and Bitcoin keeps it economic majority. Check the other threads before making the same question over and over again.

To do this, you will probably need 2 devices.

1 connected to the internet (watch only)
1 not connected to the internet (the wallet itself)

To create those wallets:

• 1. In your connected device: open Electrum to create a new wallet and choose: Standard wallet -> Use public or private keys -> Paste your public key (address); This will be your watch-only wallet.
• 2. In your offline device: do the same as step 1 but with your private key instead of public key.

When you want to spend your coins:

• 1. Go to the connected device, open Electrum -> "Send" -> Fill the address you want to send the coins to and the amount.
• 2. Click "Preview" -> "Save" -> Save the txt file with the unsigned transaction to your flash drive.
• 3. Now go to your offline device and open your offline wallet -> Tools -> Load transaction -> From a file.
• 4. Choose the txt file with your unsigned transaction from step 2.
• 5. Click "Sign" -> "Save" -> Save the signed transaction to your flash drive.
• 6. Now, go to your online device again and:
• a. Broadcast the transaction from a website (e.g: https://live.blockcypher.com/btc/pushtx/).
• b. Load the signed transaction file (just like the step 3) and click "Broadcast" to send the transaction.

Edit: This video follows the same proccess described above - https://www.youtube.com/watch?v=DQumISxkJsQ

No. Only BBCode is accepted and those are the rules per each rank:

Coinbin isn't storing your keys anywhere. As I said, "you can download the website source and run it locally (without internet). You only need an internet connection to push transaction.";
Electrum is still better and safer, but the OP is asking for a wallet similar to MyEtherWallet. And I suggested him one.

---

That's an easy fix. Don't let anybody get your email and password?

Are you talking about a Coinbin generated Time Locked Address?

If so, make sure you go to Coinb.in and do the following:

1. Go to New -> Transaction[1].
2. Paste your redeem script and click Load.
3. Paste the address you want to send the coins to at "Address" and the amount (minus fees) at "Amount".
4. Click Submit and copy the result.

5. Go to Sign[2].
6. Paste the output from the New Transaction page and the private key from the address you choose when generating the Time-locked address.
7. Copy the signed output and broadcast[3] it.

I did this exactly proccess last week with an address I had and it worked without any issues.

You could have spent 10 seconds of your life to at least read the first 2 lines of the thread where OP links his GitHub repo and says that "BTC Sniffer is a Python script" instead of posting this.

Edit: LOL. Just saw after the last post that this was posted 5 years ago.

Yes. The only way we can see Segwit's at full capacity and lower fees is if more people start sending Segwit transactions. Current only ~9% of all Bitcoin transactions is using Segwit.

Yes. You need the Address to fund it with coins and the private key to spend them. This wallet from Coinbin also lets you see your private keys, so you can use it on any other wallet software.

You can buy Bitcoins directly from GDAX (Coinbase exchange) to avoid paying Coinbase's fee. Check this video[1] for more information.

You clearly don't know how MEW works. It's basically just a client-side page for your wallet. Nothing is stored anywhere other than your wallet file that is used to open and manage your wallet or nothing at all if you want to open your wallet with its private key.

And now you are saying that Blockchain.info - which wallet is stored in their database - is "quite secure"; Even after your comment saying that you wouldn't "touch anything which exhibits on the web" (?).

---

If you are looking for something similtar to MEW, I suggest you Coinbin[1], which is open source, don't require any internet connection and can be used from any PC if you have the email and password chosen when generating the wallet.

ZCash is tagged as "evaluating" in Exodus roadmap - with this comment: "If the Zcash network remains stable and has continual upgrades it is likely we will support this asset in 2017."

About Monero, I posted this last week:

There are a lot of ways to see SegWit2x and how can it be bad or good.

Some reasons why the fork is bad:
- It is a hardfork, so there is a risk of a permanent fork.
- It is a blocksize increase, so less people will be able to store the whole blockchain.
- Core is not in favour of a blocksize increase.
- The 2x is pushed by miners, who were not supposed to be able to control the protocol.
(source)

If you have X Bitcoins before the fork, after it happens you will also have the same amount in the other chain.
Example: If you have 1 Bitcoin, after the Bitcoin Gold fork you will have 1 BTC and 1 BTG. The same also happens with SegWit2X. If you have 1 BTC, you will also have 1 B2X in its chain;
