Sending the old Bitcoins can sometimes be more expensive than wire transfers and slow compared to other crypto currencies. The transactions are also trackable. With all the fighting about what to implement going on, major improvements to Bitcoin come slowly if at all.

Thus Bitcoin 2 had to be born. Bitcoin 2 solves those problems and is also fast enough to be accepted as a payment method by retail shops and grocery stores due to the SwiftTX feature.
Yes, a Bitcoin transaction is not valid in the Bitcoin 2 blockchain and vice versa due to the differences between the transaction formats and the blockchains.
Easiest way would be to send your BTC2 to the staking web wallet. Staking would begin automatically and continue without interruptions.

But if you want the full rewards, just download and install the Bitcoin 2 Core Wallet, let if fully synchronize and then import or send your Bitcoin 2s there. Then all you have to do is keep the application running. Staking will begin automatically 101 confirmations/minutes after you get the first coins if the wallet is unlocked.
Everybody using the Bitcoin 2 Core wallet or leaving it on helps run the blockchain all the while earning Bitcoin 2s.

A staker who creates a valid block gets rewarded up to 0.6 Bitcoin 2s until the maximum supply has been reached. The staker also gets the transaction fees for that block.
Check here. The more Bitcoin 2s you have in your Bitcoin 2 wallet, the higher the chances and frequency of getting block rewards. Only a small portion of the coins in circulation are being staked at any given time so you do not need to own a lot of Bitcoin 2s to be able to get block rewards.

You can use this third party calculator to see how much BTC2 you can expect to make with your balance.
Staking the BTC2 that you have in your Bitcoin 2 Core wallet starts when you have a fully synchronized unlocked wallet that has coins that are mature enough for staking (101+ confirmations).
Only transaction outputs of 0.01 BTC2 and bigger can stake.

A green icon will show at the bottom right if you are staking. Click Tools - debug console and type: getstakingstatus to see what is wrong if it is not green.
No more than Bitcoin. The number of Bitcoin 2s in circulation will only increase by about 0.5% - 1.2% per year until the maximum number is reached.

The number of Bitcoin 2s in circulation will never increase beyond 21 million, making Bitcoin 2 a much better store of value than any fiat currency.

At the current rate, in 10 years there will be almost double the amount of US dollars in circulation! This is why investing in gold or Bitcoin is so popular.
zBTC2 was the anonymous version of Bitcoin 2 that used the Zerocoin protocol. You could convert your BTC2 to zBTC2 or vice versa in the wallet.

Bitcoin 2 Core developers alongside with any new contributors will work on: Bitcoin 2 Decentralized Exchange Network and continue to implement any further important advances in cryptocurrency technology such as the Dandelion Protocol.
Our long-term goal is to partner with a mobile point of sale payment service or creating one with rewards in the mobile app to entice users and create more real world use for Bitcoin 2.
Anyone interested in developing Bitcoin 2 further can contribute to the Bitcoin 2 github.
It works just like the "InstantSend" feature in Dash. When a user chooses to send a transaction as a SwiftTX, the transaction will be sent to Masternodes to process and it gets verified and guaranteed by them almost instantly.

Thus there is no need to wait for the transaction to appear in a confirmed block. This type of payment is made for Point of Sale situations in the real world.
They process and guarantee the SwiftTX transactions along with adding to the speed, connectivity and redundancy of the network.

The Masternode at the head of the queue-like system gets rewarded on every newly created block, regardless of who created the block. Most of them also get included as seed nodes after they have been online long enough. Seed nodes are the first nodes that new wallets connect to in order to find peers.
You will need to have 1000 Bitcoin 2s as collateral that you can unlock and spend at anytime and use an easy managed masternode hosting service or run a VPS or a server. You can Read more about running a Masternode for Bitcoin 2 here.
You can check that figure at the top of the Bitcoin 2 Block explorer.
Just download the newest .zip/tar.gz file, shut down your wallet and wait for it to finish shutting down. Then copy the executable files in the bin folder to replace the ones you had installed already.

If for example you always used only bitcoin2-qt.exe, then you only really need to replace that older bitcoin2-qt.exe file with the new bitcoin2-qt.exe. Your coins are unaffected when you upgrade like this and you will see them with the new version too.
In some cases downloading a snapshot can be faster. So you can just download this Bitcoin 2 blockchain snapshot and follow the instructions in the ReadMe.txt.
Windows
Go to Start > Run > %APPDATA%\Bitcoin2
(or just enter the above path in explorer)

or C:\Users\%username%\AppData\Roaming\Bitcoin2


OSX (MacOS)
Open a finder window, then select the "Go" dropdown menu. In this menu please press the "Go to Folder..." option. In the window that opens type: ~/Library/Application Support/Bitcoin2 and press enter. If the folder cannot be found please repeat the steps and enter: ~/.bitcoin2

~/Library/Application\ Support/Bitcoin2
(/Users/YourUserName/Library/Application\ Support/Bitcoin2)
Or: (/Users/YourUserName/.bitcoin2)

Linux
~/.bitcoin2 (hidden folder)
You will need to copy the wallet.dat file in the data directory when the wallet is not running. (Bitcoin 2 Core should be shut down before copying). Backups of this file are created automatically to the backups folder inside the data directory.
See the above question if you need help in finding the data directory.

In order to restore a backup or move your wallet to a new computer, you just have to install Bitcoin 2 there like normally, and then copy your backup of your wallet.dat in the newly installed data directory when the wallet is not running. (Bitcoin 2 Core should be shut down before copying).
Make sure you have the latest wallet version. If that does not help, try restarting the wallet if you did not already. If you have less than 4 connections/peers after the wallet has been running for several minutes, try disabling any firewalls and if this is not your first time running the wallet, you could try deleting the peers.dat and banlist.dat files from Bitcoin 2 data folder. Then start the wallet again. If that does not help and the wallet shows that you have more than a few connections/peers, then click to go to Tools - Information - and click the "delete local blockchain folders" button to let it resync.
Since June 2019, we started making claiming BTC2 from the Bitcoin fork more difficult. They had been easy to claim for 15 months already, which was plenty of time and that was a good start to our blockchain and distribution.
It is no longer possible to import Bitcoin private keys that have an unclaimed BTC2 balance and the unclaimed balances cannot be spent.
In some cases someone else creates a block a little bit before you and gets it transmitted and accepted by the network before your wallet receives that block. Meanwhile you had created a block and received a reward that turns out to be in an orphan block and thus not accepted by the network. The wallet then marks it red as an orphan transaction.

It happens to everyone and it does not affect your holdings nor expected staking ROI unless you are getting more orphan rewards than rewards that stick, which would indicate a reliability issue with your internet connection or computer, or perhaps your system clock is not accurate (should be within seconds of the actual official time).
Short answer:
Use a fully updated Raspbian and the ARM 32 bit version of the wallet.

This may happen when the app was not shut down properly. For example due to power failure. This is usually fixed by a resync, which the app suggests to do anyway when needed.

You can also do that by passing -resync as a command-line argument when launching it, or by manually deleting the folders blocks, chainstate and database inside the Bitcoin 2 data directory.

But if the words CDB: Cannot open database appear, most likely it is a sign of a corrupt wallet.dat file. First make sure the wallet is not running. Then:
Step 1: make a backup of the backups folder inside the Bitcoin 2 data folder.
Step 2: move wallet.dat there, and copy a wallet backup with the last known working date in the file name into the main Bitcoin 2 data directory, where you took the wallet.dat out of. Then name that wallet.dat and try to launch the app again.
