How do you take care of your cryptocurrencies not being stolen?
Most of us know that keeping your funds on exchanges isn't safe by any means. Now online wallets that you can access via web browser or even smartphone aren't safest as well. Hardware wallets can be probably hacked (although you can encrypt the wallet.dat file, is that enough for hackers to not stole your money?).
The best way to keep cryptocurrencies is physical wallet like Trezor / Ledger Nano S. But if you connect them to your PC are you surely safe? Let's say that your PC is infected with some sort of malware that's focusing on stoling your private key or something like that. Are you still safe?
Even your wi-fi can be compromised and infect your devices connected to the network.
I want to secure my funds, so what is the best way to make sure your cryptocurrencies are safe and sound?
The safest wallets against theft are hardware wallets such as Trezor, KeepKey, Ledger, etc. You can use them on an infected computer because they never reveal their private keys and they ask you to verify the address that you are sending to. |

Ok. I read the white paper. Honestly, I don't think there is much there. Consider that the "main feature" doesn't even use the Oxycoin token. What exactly are you getting when you buy a token? You aren't getting a share of the company. The main feature of the OXYCOIN® mobile application is to enable users to purchase cryptocurrencies directly with FIAT - whether they have IT knowledge or not. OXYCOIN® provides a user-friendly platform that contains all the information and tools needed by any crypto-enthusiast and puts it right at their fingertips. With OXYCOIN® our users will be empowered to make informed decisions and take positions in crypto-markets effortlessly.

Hi guys, I want to start using bitcoins. Is this how it works? I create an account at Coinbase and get a bitcoin address. Then when I sell something, the buyer sends bitcoin to my Coinbase bitcoin address. I can then cash out through Paypal etc.?
Coinbase also has merchant services that enable you to add a pay-with-bitcoin button to a website. If you link a bank account to your Coinbase account, they will deposit money directly to your bank account. |

Despite what others have written, it is possible to use LocalBitcoins with SWIFT. However, SWIFT transfers take a while and there might be other more effective ways to buy. In your case, set up the transaction when you are ready to send the money. Don't do it on the weekend or during a holiday or at night when the banks are closed, obviously. Once the money is sent, mark the transaction as paid. You will probably need to give the seller information about the SWIFT transfer. After you have paid, the window is no longer relevant. The seller will release the bitcoins when the money is received. In the future, I suggest asking Localbitcoins questions in the Localbitcoins forum. https://localbitcoins.com/forums/ |

Steemit has its own currencies. It doesn't use Bitcoin. |

I have bought gold coins from JM Bullion with bitcoins ( https://www.jmbullion.com). They give a small discount over credit cards and they ship immediately. If you don't want to take delivery, then Vaultoro ( https://www.vaultoro.com) is an option. |

I just noticed that I send the bitcoin to the same address as I received it from. I'm not learned, but if I send bitcoin to a send wallet then they are lost?
The question is who owns the address you sent the coins to? If the coins came from your localbitcoins account, then you can explain the situation to localbitcoins support and you might get your coins back. |

If the proper deposit address is 1D38x...GnHa, but the coins were actually sent to 1Mihu...AuqU, then Bitfinex won't be able to help you unless they control the address 1Mihu...AuqU.
Where the bitcoins are sent from is determined by your wallet, so it might be completely normal for your bitcoin to be sent from 1HjCQ...8weL. Without more information about your wallet and previous transactions, it is not possible to explain why bitcoins came from an unexpected address.
It is possible that you are a victim of a hack that changes bitcoin addresses in the clipboard to the hacker's address. Try copy/pasting that address again to see if it changes again.
But if you look at the transaction funding 1HjCQ...8weL, you will see that the coins came from 1Mihu...AuqU. You apparently sent the coins back to where you got them from! So, if your information is correct, then the hacking scenario is unlikely, and it is more likely that you somehow accidentally sent the coins to the wrong address.

1. Backing up a wallet ensures that if the wallet is lost or destroyed, you can restore it. It does not protect you from being hacked. Most wallets use a "seed", and that is what must be backed up, but each wallet is different. 2. You will need all the normal stuff used to set up a LAN connected to the internet. Bandwidth requirements are not high. You will need cooling equipment. 3. While the bitcoin network is safe, your mining operation could be a target. You must assume that somebody is going to try to hack into your network, steal your bitcoins, and redirect your miners to their own account. 4. Whether you go solo or join a pool really depends on how often you want to get paid. In a pool, you get bitcoins every time the pool finds a block, while if you go solo you get paid every time you find a block. The result is about the same in the end, except that the pool takes a cut. At the current difficulty, 140 TH/s will average 1 block every 328 days. I recommend joining a pool. 5. Don't use that calculator. The problem with that calculator is that it doesn't consider a rising difficulty value, so it is only accurate for 2 weeks at most. The Bitcoin Wisdom Mining Calculator is much better for long term calculations. |

I'm not Coinbase support, so I'm just guessing here. I believe that you are trying to set up the ability to send/receive money via bank wire, and they are telling you that you first need to set up the ability to send/receive via bank transfer (aka ACH or SEPA) with that account first.

Hello, I am using the latest bitcoin-core, 0.14.2. I went to this page to estimate the transaction fees: https://bitcoinfees.21.co/api/v1/fees/recommendedAt the time of writing this post: fastestFee 300 So, I went and setup 300 / 100,000 as txfee: bitcoin-cli settxfee 0.003 true However, I can not send out anything. bitcoin-cli sendtoaddress 1FBpQU...............KyRLEu 0.0010 error code: -4 error message: Error: This transaction requires a transaction fee of at least 0.001122 What can be wrong here? My guess is that you have less than 0.002122 BTC in your wallet (0.0010 plus the 0.001122 transaction fee). |

Best coin for day traders, pumpers, short term investors, long term investors and potential investors.
Currently the best coin to invest in for huge profit is Bitmxittz BMXT ...
Thank you for that perfect example of a classic "pump-and-dump". |

There is always a small dip when Bitcoin price insanely increases. Always wait for such dip and keep on buying. I tend to hold my BTC for long term while buying more at dips as one is going on now. Never buy at pumps. Always wait for a correction even if it is small.
The flaw in that advice is: 1. The bottom of the next dip might be above the current price. 2. The dip might continue going down after you buy. Timing the market should be left to people with super-powers. If you don't have the appropriate super-power, then don't try to time the market. |

Nothing is 100% safe. Look for the storage method that fits your needs and your desired level of security, and learn how to manage its weaknesses.

Please help me out! I am a noob.
Q. If I purchase BTC through Visa Card in my Cex.io account, will they allow me to transfer my BTC amount in my Blockchain.info wallet?
Also let me know if thr is any-other safe place to purchase BTC from Visa Card.
1. Get an address from you blockchain.info wallet from the "Request" tab. 2. Find the "Send" feature in your cex.io account. Sorry, I've never used it, so I don't know details. 3. Enter the address you got from your blockchain.info wallet and the amount, and send. 4. The bitcoins will be sent to your blockchain.info wallet. Cex.io is probably safe for buying BTC with a credit card, but no exchange or other custodial wallet service (such as cex.io or coinbase) should be considered safe for holding funds. Those types of sites have a long history of losing or stealing customer funds. Blockchain.info is different, but wallets accessed through a website have additional security risks. |

Where did you get that address?
Does it belong to your Coinomi BTC wallet?
Perhaps you sent to an address in your BCH wallet and not your BTC wallet.
Perhaps you are looking at your BCH wallet and not your BTC wallet.
If you go to the "received" tab and click on "previous addresses", the address should be there.
