1. Yes.
2. Maybe.
3. Huh? What does a 51% attack have to do with a smart contract replacing a government?

Technical Analysis is investment astrology.

This is a classic ponzi scheme where you invest money and they pay you a fixed return. They claim they make a return on your invested money by "trading", but that is a lie. They pay you from the money coming in from other investors.

There is also a pyramid scheme involved, where they will give you money if you convince other victims to invest.

In short, do not give them your money. It is a scam.

Here is the video. If you watch it, please don't forget that no matter how friendly the guy seems or how good the opportunity looks, it is all a lie.

No.

Why Coinbase? What do they have to do with this?

The unknown address is a "change" address in your wallet. That's how a Bitcoin transaction works. It is a lot like paying $5 when you only have a $20 bill. The transaction sends the extra to a new address in your wallet.


If you were expecting 23,700 ADA, then again, that is how a transaction works.


The Trezor confirms that everything worked as intended.

1. Because of the way a Bitcoin transaction works, sending bitcoins typically involves sending more than you want. It's kind of like you want to pay $5, but all you have is a $20 bill. The extra amount is sent to a newly created address in your wallet called a "change" address. That is the second output in the transaction. The wallet can spend coins in that address just like any other address it manages.

2. When you "import" a private key, the new wallet simply copies and stores the imported private key and uses it just like any other private key that it manages. When you "sweep" a private key, the new wallet sends the bitcoins held by the private key to itself using a normal bitcoin transaction. Many wallets (especially ones that use a seed) do not have the capability to store an imported private key, so they "sweep" it instead.

Also, you (like many others) are confusing the terms "wallet" and "address". A "wallet" is a container for private keys (and the associated addresses). An "address" holds bitcoins. There is really no such thing as a "wallet address" because a wallet typically has many addresses. My Mycelium wallet has over 400 private keys/addresses.

"coin" is just a nickname for a cryptocurrency.

"I bought some coins from Coinbase today. I spent $100 on bitcoins, $100 on litecoins, and $100 on ether".

He says, "Hey baby, I got 30 million satoshis."
She says, "You're an idiot if you think that impresses me. I've been hodling 100 BTC since 2012."

Blockchain.info gives you exclusive control of your private keys.

1. There is nothing about the upcoming hard-forks that affect the safety of your bitcoins. After the fork, if the blockchain.info wallet doesn't do what you want it to do, you can always move your keys to a new wallet.

2. You will get coins because you have complete control of your private keys. However, blockchain.info can't do much to help you get them because they don't have access to your private keys.

3. There are (or will be) plenty of places that explain how to get coins on both sides of the fork. No reason to explain it again here.

People seem to have very short memories. Was the fall in price in 2014 from $1200 down to $200 just taking momentum?

I suspect that this is a bluff, and his plan is to freak everyone out with talk of more forks so that people react by rejecting all forks, especially segwit2x.

Smells like a pump-and-dump scam. Nobody can be right 98% of the time.

Yawn. It is already "close to $8,000".

831 minutes is the time between when blockchain.info first saw the transaction and when it was added to a block.


I think that blockexplorer.com uses your local time, because the time it shows me for that block is 5:16:25 PM.

Blockchain.info shows the block's timestamp in the transaction information:

If you have a blockchain.info wallet, then you have exclusive control of your keys. After the fork, if you don't like what they are doing, you can move your keys to another wallet.

A blockchain.info wallet is not dangerous. At the worst, it might be inconvenient.

Each block has a timestamp that is generally close to the actual time. You can look up the transaction and get the block it is in. Then, find out information about the block.

If that transaction ID cannot be found then the bitcoins have not been sent. Also, when sending from a wallet that is not connected to the bitcoin network, the wallet will hold the transaction until it can connect.

Where are you sending the bitcoins from? Is it from your own wallet, or is from a mining pool? More details about where you are sending from would be helpful.

If he said that instead, I would totally agree with him, and I own several bitcoins. I'm not selling because I don't know when it will pop and I'm in it for the long term anyway.

As for all the people dismissing what he said for whatever reason, you need to put away your fanboy excitement and take a cold hard rational look at what is going on. Sure, Bitcoin has the potential to change the world, but that is not what is driving the price right now.

Have you contacted Gemini customer support? If the transaction is confirmed, only they can tell you why your account has not been credited.

1) Yes, though you don't have to sell your BTC, and you can only send btc gold to the ledger nano if it supports btc gold.
2) In simplest terms, a private key is like a password for an address. If you copy a private key from one wallet to another, then both wallets have the ability to spend the bitcoins at that address. Some wallets "sweep" a private key instead of importing it. When you sweep the private key, the new wallet uses it to send the bitcoins to itself. So in that case, it is just like sending the bitcoins from one wallet to another.
3) Many wallets don't store private keys, so you can't import them, only sweep them.
