One? Here are six. - Don't invest in anything that you don't understand well.
- Don't invest in something just because somebody says to.
- Invest for the long term.
- 90% of ICOs are outright scams and a legitimate ICO has no more than a 10% chance of succeeding.
- Assess risk appropriately. A concept is a long way from a working demo, which in turn is a long way from a finished product.
- Technical analysis is financial astrology.

Unlike Bitcoin, the primary purpose of Ethereum isn’t to become an alternative to money or payments. Rather, its purpose is to pay for smart contracts, transaction fees, and other services on the Ethereum network.
It's purpose is determined by the people that use it. Right now, its primary purposes are to invest in ICOs and to breed illustrations of cats. |

I imagine that it is the same reason that younger people like investing in Gold/Silver.

The actual value that must be achieved is the "target" as represented in the "compact" form. When the next target value is computed, the result of the computation is converted to the compact form to get the actual value that is used. The difficulty is derived from the target.
I don't know why the target is stored in the block header, since it must be computed for validation anyway and it doesn't vary.

what a shame here it costs 0.082 $ kwh while its an oil rich country !!... I think if you get free power you double or triple your profits or even better, for example the S9 will cost me 70$+ in electricity every month ! and earnings just 45$/mo, its all about power i guess  Are saying you pay $70 in electricity for $45 in coins, or is that $45 after deducting the cost of electricity? |

Today I wanted to check my ETH amount in an exchange.
However, due to laziness to enter all the passwords and 2FA etc,
I decided to just check my exchange ETH address via ETH explorer.
I copied it and pasted in in an explorer and what I saw amazed me:
Balance: 0.00013284416 Ether
There should be atleast 2 ETH!
I checked the transactions below and saw that RIGHT after an incomming transaction happens,
another outgoing transaction empties my exchange wallet!
I logged in right away to the exchange and the coins were there!
Does anyone know, how come exchanges use our money for their own things
but they don't pay us interest? Or is there an exchange, which pays interest?
You don't have a wallet at an exchange, you have an account. That address is a deposit address in the exchange's wallet. It works just like a bank. Your money is combined with everyone else's money. |

Someone propose that I make getnewaddress and dumpprivkey that address,
he will do same at his wallet, and we exchange each other's privkey generated from above, then importprivkey.
and if I input coin to there, that become multisig, both signing need and safe.
Is this true?
No scam factor here?
That is not how multisig is done. Do not share private keys. If you give someone a private key, then they can spend the bitcoins at its address. Multisig is done like this: 1. One person creates a transaction and signs it, and then sends the signed transaction to the other person. 2. The other person also signs the transaction, and then broadcasts it to the network. |

Perhaps you could split the process into two.
The first process generates private keys and tracks new orders. Assuming that the keys are generated deterministically, it would have no problem tracking millions of addresses.
When the first process detects that an order is paid, it hands the private key to the second process, which maintains the wallet. This way the wallet only tracks the keys with funds.

And maybe it is because he is Satoshi!
It's a stupid article and not worth reading. It is typical Coin Idol grade school journalism.

If your electricity cost is $0.082/kwh, then the mining cost is probably about $1-$2 per day. If your revenue is about $1-$2 per day, you are not making any money.

Apparently the scammer got your email and password from a list of leaked passwords. The best thing to do is to ignore the threat and change all of your passwords. It is best to make each password unique, and never use a popular or easy-to-guess password like "qwer1234". Here is more info: https://twitter.com/el33th4xor/status/1017094434209652738/photo/1 |

An extended public key could be used to generate an unlimited number of addresses, but there would still need to be some coordination between the sending wallet and the receiving wallet. You might as well provide a unique address for every customer. It is easy enough to print one on the receipt or on a screen.

This is a ponzi scheme. No legitimate investment can offer those kinds of returns.

Ignore. He probably sent that same email to thousands of people. But, if you believe that any of his claims might be true, then wipe your computer to remove any malware, and then change all of your passwords.

Another issue is that any fork in the block chain might result in transactions that are valid on one branch being considered invalid on the other branch because the references to the outputs in the competing blocks would be different (assuming that the reference is determined by the miner).
