I really appreciate threads like these because they fairly express feelings without trying to be hostile. The reality is that Cardano has been an ongoing project since mid-2015 in one capacity or another and only recently did the initial participants have a chance to exercise liquidity. The price didn't suddenly go up exponentially due to a big pump rather it was a reflection that two years of progress have occurred from setting up research centers to developing the core client since the last price signal.
Finally there original market was scoped to Asia and now a much larger set of people are considering Cardano. It's reasonable to assume a dramatic shift and lots of volatility.
Why so many coins? |

If I wanted to write down my private keys by hand, and use them in Bitcoin cash wallets, how safe would it be to disconnect from the internet, open the wallet, and jot the private keys down by hand? (Let's say I'd rather send a single private key that controls one address with a small amount of BTC rather then hand over my wallet seed to a Bitcoin cash wallet)
In other words how bad would my computer need to be infected for this to still be a potential problem?
Can these viruses still take screenshots or monitor keystrokes even if my machine is offline, and then send them back to whoever infected my computer after re-connecting to the internet?
Or am I being overly paranoid? Anyone with enough hacking knowledge who can give some detail as to what the worse viruses with the worst case scenarios could do, even if you're opening up the wallet offline?
I'm sure some people like me would want to know.
You should send your coins to a new Electrum wallet after the fork before using your private keys in any Bitcoin cash wallet. That is actually mentioned with https://electrum.org/bcc.txt under "How to redeem my BCC?" When you say "send your coins to a new Electrum wallet", does that mean source another computer, download Electrum on it and send the coins to that new wallet? Or can I just make an additional/second wallet with a new seed phrase on my existing desktop with Electrum? |

I went ahead and dumped the private key. It starts with a capital L. I thought it was supposed to start with a 5. What does that mean?
This is okay, as there's actually two types of private keys, uncompressed (WIF starts with a 5) and compressed (WIF starts with a K/L). The only difference is that the compressed keys are suggesting to generate the address from a compressed public key, while the addresses generated with the ordinary keys are generated from an uncompressed public key. If you have the private key of any format, both the compressed and the uncompressed address are yours. By the way, if you use bitaddress.org (I don't recommend it though, if you ever use it, DOWNLOAD RUN ON AN OFFLINE MACHINE), keep in mind that you have to use the compressed address in the Wallet Details section. Ok, so now that I have the private key, what specifically(in the most layman terms possible) should I do with it to safely get my coins into a new wallet? My knowledge is clearly lacking and I don't want to screw this up obviously. I have a breadwallet and just started a blockchain wallet. Can it(or should it?) be done with either of these? I don't intend to ever use my old desktop again(aside from photo storage etc), I just want to safely get my coins out ASAP. |

Ok, so I'm assuming that the transaction that you sent to your friend is showing in your transaction list (as unconfirmed)? If you are using 0.14.1, you should be able to right click on the transaction in the transaction list and select "Abandon Transaction".
If that doesn't work, then I would suggest shutting down your Bitcoin Core client... and restarting it using the "-zapwallettxes" commandline option... This will remove all unconfirmed transactions from your wallet, which, in theory, should then mean that your balance reflects what is in your wallet.
Having said that, if you wallet is not synced, and there are transactions on that address AFTER the last block that has been synced, you may get an incorrect balance.
I take it you still haven't been able to get the sync working? What version of the Bitcoin Core client are you using?
EDIT: Actually, it probably won't really matter... if you can see your addresses, proper balance or not... you can still dump the private keys... once you import the private keys into another wallet, that wallet should be able to scan the blockchain and get the correct transaction history and balance for your address.
It was showing as unconfirmed as you said. I am using 0.14.1. I abandoned the transaction. It still isn't showing up in my balance though. Currently it's a year behind, but moving at .2 to .5% per hour. EDIT: I closed and re-opened the wallet and the correct balance is now reflected, thank you for that! But I know very little about importing a private key into a wallet, or which wallet I can use a private key with for that matter. EDIT II: I went ahead and dumped the private key. It starts with a capital L. I thought it was supposed to start with a 5. What does that mean? |

Hello all, noob here. I bought a little btc in '13 and have had it in my desktop(HP Pavillion p6720f) core wallet ever since. I have been unable to sync with the bitcoin network. I lost my 12 word recovery phrase. The wallet opens and I have the wallet passcode, it's just not synced. Is/are there any alternative way/s to get the coins out? I would greatly appreciate any assistance.
Bitcoin Core (aka Bitcoin-QT) never used 12 word recovery phrase. Also, it has only had HD support as of v0.13.0 which was released in August of 2016. If you have had the wallet since 2013, it is NOT an HD wallet. It is just a "traditional" wallet comprised of a collection of private keys. Have you upgraded to the latest version? (currently v0.14.1)... if not, this may explain why you are unable to sync. If you have upgraded... and still can't sync, is your instance connecting to the network ok? If you goto "Help -> Debug Window -> Information" what does it say for "Network Connections"? It may be your firewall and/or router blocking the inbound/outbound connections. If you just want to move to a new wallet... Goto "Help -> Debug Window -> Console" and then: 1. use the command to see all your addresses. (As a bonus, it also enables you to see which ones contain coins  ) 2. use walletpassphrase "YOURPASSWORDHERE" 600 to unlock the wallet for 10 minutes (600 seconds)... you can use whatever number you like, just make it long enough to give you time to get all the keys out 3. use dumprivkey "BITCOINADDRESS" for each of the addresses you got in Step 1. You can do all, or only the ones with coins, it is up to you and whether or not you expect to receive payments to these addresses in the future. 4. Sweep (or Import) the private keys from Step 3. into the wallet of your choice. Sweeping is the recommended procedure as it effectively moves the coins to the new wallet/address... whereas import keeps them on the current (and now 'exposed') private keys... Thank you for the response. I copied my wallet.dat file to a USB drive. What would you say the minimum requirements are for a computer to be capable of downloading all blocks/syncing to the blockchain? I don't want to waste the time if the next computer I try can't sync either. Any idea?
Minimum specs here: https://bitcoin.org/en/bitcoin-core/features/requirementsI tried the debug window and list adresss groupings. Next question/issue: it's showing zero balance. A while back I sent the total wallet contents to a friend and because the wallet wasn't synced, they were never sent. But when I type in my wallet address on the blockchain, it shows the correct balance. What do I do in this case? |
