You can also wake up and find that another coin or version of BTC took over, and your coins are worth nothing.


Or that Bitcoin is overregulated and they are worth cents, and hard to sell and buy.

Bitcoin went from nothing to something, going from something into a big stuff is way harder

The United Nations would not allow any of those bad things to happen.

In 15 days or so the myth that Bitcoin price will ever be higher than 1 year before, no matter when you bought, will be busted.

How are you feeling?

Or do you think we will see another rally in one week?

If we told you, how would it make you feel?

They say this because bitcoin has Ben going down steadily since $33.  Grin
2125  Bitcoin / Bitcoin Discussion / Re: Does it exist a bitcoin wallet with 2FA? on: October 29, 2014, 09:59:24 AM
2FA is really not good for wallet security as all that 2FA does is rely on a 'trusted' third party to only give someone access when they can enter a code that is delivered to a device. This essentially means that you must give up access to the private keys to a third party, which in itself is a bad security practice.

This is a very good summation of the issue. If you use a wallet that is not completely and solely under your control, you're gonna have a bad time. If your Bitcoin keys are on another service - if signing transactions happens anywhere else but on your computer - then you are vulnerable to attack.

Internet two-factor authentication schemes prevent simple password-stealing attacks, but assume a secure unalterable communication channel, which is a bad assumption. SMS codes, challenge-response, time-based one-time passwords, yubikey, all can be proxied by an attacker and instantly replayed to the actual service.

Secure communications require encrypted and signed channels, such as done through a Java smart card provided by the internet service, which relies on the device also not being security-degraded by secret arrangement with a three-letter agency.

Look at blockchain.info wallets - in theory secure, but in practice any man-in-the-middle (such as a Tor exit node, your VPN company, hacked service home page with injection, or government tapping/redirecting the connection) or even man-on-the-side (with the poor security of https encryption) can intercept your communication with the service and steal your credentials, secrets, and Bitcoins. Since the something-you-have also goes over the wire, this provides very little security to an attacker in these positions.

With Bitcoin, you must be your own bank. You cannot ask for a refund when you are defrauded.

Real personal two-factor relies on something you have along with something you know. Something you know is your password to the encrypted wallet. Something you have is your local computer with the Bitcoin wallet. If someone else doesn't have both of these, they can't send Bitcoins.

Another layer of something-you-have/something-you-know can be a two-layered encryption scheme for accessing the local device. An example would be a smart card OS drive encryption in combination with a password-based hardware drive encryption.

A further layer would be to use a TPM module for OS full disk encryption, this requires something you know (password to unlock TPM) and something you have (motherboard/system TPM) to access the drive. The drive separated from the security device is also useless.

If you want another layer of security, lock every Bitcoin wallet storage device or computer in a safe. Then to access it you need something you have (a safe, a key) and something you know (a combination).
This covers it well. Wallets (online or not) don't need access to your keys, they only need the authority to broadcast signed transactions.

Bitcoin can't die. Only the weak hands will.
2127  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: October 29, 2014, 09:41:25 AM

so yeah an irrational doubling of btc would be nice vs the irrational halving of price of the last few months

it should be incomprehensible in both directions imho just to be fair Smiley

**crickets**

Sure has gotten quite around here, all of a sudden.




just a warning i had someone who owed me 6.3K usd ...told him he could pay me in bitcoin....as soon as it hits my address btc will tank

just a public service warning......I'm 4 out of 4 on such stuff no reason it won't go down 5 out of 5 in the same manner Smiley

Really? For how low a price are you willing to tank your bitcoins?
2129  Economy / Speculation / Re: Be that guy on: October 29, 2014, 06:50:19 AM
Hashrate is still climbing. If you can buy below cost, then what's the problem?

according to KNC, the mining cost of bitcoin is significantly below $400, i think it's around $170 per coin and they are trying hard to mine more and dump more

KNC 3T miner at 1710 Watts: $5995 (of cause the cost of manufacture is under $3000)
mine 1 bitcoin: 3.412 week, Power Cost: $98
let's say you mine 50 bitcoins and stop mining, cost per coin: $158

Few miners get that efficiency or have electricity that cheap. Their equipment gets more obsolete every day. A 100% markup is fine for seasonal retail, but I doubt miners are making such a gamble or wasting their talents on a one time shot at short term gains.

Lol you've got to laugh at these childish scammmers. Nobody is going to fall for this and certainly no one is going to pay it. They're just trying their luck. Hope they get caught.

hate those guys who spread some horrible news to panic us and they should be punished to make sure the order of our society.
You're talking about Fox News, no?
2132  Economy / Speculation / Re: Gold collapsing. Bitcoin UP. on: October 28, 2014, 04:50:09 PM

I know next to nothing about dogecoin (or any alt really) because they don't interest me much, but judging from my friends who are kind of interested in them I'll predict they'll have an OK future. 


Can I ask how long you've been holding Bitcoin? Did you friend see you profit from the previous bubble? Do these people not want to make money or is their capital investment in Dogecoin trivial?

I'm really confused how these people would be holding stash of doge throughout different Bitcoin rallies and not get greedy.

Doge could make it but I think Bitcoin is still a way better bet; Gold is a very good conservative (compared to Bitcoin) bet as well

I don't see how the monetary features/economics of Doge can make it in the long run. I think it's a fad.
Yeah, Doge is pure marketing hype. I'm surprised they didn't try to make it this years Christmas gift.
2133  Economy / Speculation / Re: Noticed something with charts on: October 28, 2014, 04:45:55 PM
It didn't matter if you paid $5 or $10, just as it won't matter if you paid $300 or $700 when the price bubbles again.

If you were going to buy 1000 Bitcoin, then a $5 price fluctuation wouldn't matter much.  But if you were going to buy $10,000 worth of Bitcoin, then that $5 price fluctuation means the difference between having 1000 Bitcoin and 2000 Bitcoin.  I think you'd agree that it does matter.

Only if you are a greedy person.
2134  Economy / Speculation / Re: Noticed something with charts on: October 28, 2014, 02:50:23 PM
If this pattern is any guide, there is about 9-12 months to go before the next leg up begins.
Considering the block reward halves soon after that, it's an obvious guess.

I thought it was scheduled in ~21 months?
Yeah, probably so. I would ask what patterns you are seeing, but then I would also have to ask what drugs you are on.

You do know the term "cryptic" refers to "hidden" monsters like bigfoot and the Jersey Devil.
