21  Economy / Speculation / 20 articles on 'Bitcoin is broken', researchers warn' doesn;t move price? why? on: November 07, 2013, 12:42:19 AM

some one make sense to me?

As this doesn;t make sense?

SUrely panic selling should happen, unless theirs market manipulation



----------------------------------------------------------------------------------------------------------------------------------


Academics Ittay Eyal and Emin Gun Sirer say this group could stay ahead of the competition, which would be stuck solving cryptographical challenges that have already yielded bitcoins, losing time, effort and money.

“The key insight behind the selfish mining strategy is to force the honest miners into performing wasted computations on the stale public [blockchain] branch. Specifically, selfish mining forces the honest miners to spend their cycles on blocks that are destined to not be part of the blockchain,” explained the researchers.

In time, rational miners would prefer to join the selfish miners in order to maximise their profits, and the selfish group would increase its influence until it becomes a majority. At this point, Bitcoin would stop being decentralised, losing one of its most attractive properties. Control by a single entity could even lead to the complete collapse of the digital currency.

Researchers say that selfish mining is feasible for any group size of colluding miners, as long as they have enough hardware at their disposal. Indeed groups capable of such projects already exist.

Eyal  and Sirer propose a modification to the Bitcoin protocol that protects against selfish mining pools that command less than a quarter of the overall mining resources. But they say that the virual currency will never be completely safe against this type of attack.

Bitcoin is dropping like a hot knife through butter,

But who really wasn't expecting this at all at some point, it was a matter of when than will it, and how much higher it could go before it dropped

I think we will see 50's before a gradual climb back up

what are your thoughts ?

27  Economy / Speculation / Do not panic, its not the end of bitcoin FFS on: July 03, 2013, 06:22:43 PM
Everyones panicing as if we havn't seen  a drop before, i mean by now i would think that the majority of the forum members are desensitised to drops as they have seen it in bitcoin so many times,  thats how bitcoin is, and no doubt bitcoin will go back up, its called the circle of bitcoin, if anything now s the time to buy ! 80 dollar coins! you were all thinking 80 dollar coins were cheap when bitcoin was 180 dollars, now its 80 dollars, nothings changed its still cheap

point is

29  Economy / Auctions / [Group Buy] KnC Miner Jupiter shares: $77 ~4Ghash/s (85/100 shares Left) on: July 02, 2013, 07:45:00 PM
https://bitcointalk.org/index.php?topic=244789.msg2637476#msg2637476

Leviatus crypto-mining group

We have decided to organise a group buy for the KnC miner Jupiter. We are issuing 100 shares at  bitcoins each. Price may vary based on exchange rate. 6 shares will be reserved for the organisers. 94 shares at  BTC per share will cover all costs including shipping and set-up.

Are we qualified?

Yes, we already have a mining operation which has been running for several months. We are looking to expand into the ASIC game


Are we trustworthy?

Yes, we can offer photo identification of the team behind the mining operation if needed. I have been an active member on this forum for almost a year. I have been involved in several transactions and currently run a Litecoin mining operation with an associate.


Where will the mining rig be situated?

The KnC mining rig ‘Jupiter’ will be situated in southwest London, UK. The shares issued are only for a holding in the KnC Jupiter, not part of our overall mining group. The Rigs will be covered by insurance.


When will dividends be paid out?

Dividends will be paid out every Two weeks. Each shareholder will be paid a dividend depending on the amount of shares they hold.


Why do you need an investment from the public?

We don’t, we are financially capable of ordering several of these mining rigs with our own capital, however there are risks involved when ordering from KnC miner. We want to share the risks and rewards for those that invest with us.

Any questions, Identity verification or anything else, please let us know and we shall supply it.

Below is a description of our share offering:


Payment Address - 19VeHMyaHjcTzXS2FXKasFRvwPbwXDxE9X


This group buy is intended to give forum members the opportunity to purchase hashing power through the recently launched KnC Miner (https://www.kncminer.com) company located in Stockholm, Sweden. I have structured the purchase so that members can get involved in ASIC mining using the KnC Jupiter device without having to pay the full ~70BTC for their own machine.

Offering:
- 94 shares at  each are available. (100 shares in total, including 6 shares owned by the organisers)
- Each share is worth approximately 4Gh/s of hashing power
- Each share entitles the owner to 1/100 of the BTC proceeds from a KNC Miner Saturn mining 24/7 for a minimum of 30 months*, payment will be made to the address of the shareholders bi-weekly. (*Miner breaking after 12 month warranty, random acts of nature like data center burns down, internet downtime, etc. not covered in 24/7 for 30 months. If mining is no longer profitable before the end of the 30 month period, mining will cease)
- The 6 outstanding shares will be owned by the organisers as payment for maintenance of the miner, peripheral hardware needed UPS, possible router etc.
- After 30 months we will consider decommissioning and possibly selling the miner if it is no longer profitable to run. This can be put to a shareholder vote.
- Organiser shares will cover maintenance, insurance of equipment from theft, and work including initial set up (not electricity).

IN CASE OF NON DELIVERY:
We take no responsibility for the possibility that KnC Miner does not deliver the miner. There is a certain level of risk which is taken on by shareholders, you can never 100% guarantee anything when it comes to pre-orders. By purchasing shares, you agree that you understand the risks involved and agree that the organisers accept no liability in the case of non-delivery. We will, of course, do everything within our power to recover the costs and reimburse our shareholders, less a 1% fee for our time/management.

To purchase shares, send  per share to address:

19VeHMyaHjcTzXS2FXKasFRvwPbwXDxE9X

- PM me/and post the transaction ID in this thread. ONLY use sending addresses you fully control. I will use the sending address for BTC payouts for your share ownership and if you request change of payout address I will require that you can sign your share purchase address to make this happen OR I WILL NOT CHANGE THE RECEIVING ADDRESS. This is for your own protection.

If I have forgotten anything or you require more info etc. Please feel free to ask/post in this thread.
Should the Group Buy not sell all 94 available shares within 3 weeks I reserve the right to refund all share holders their purchase price -1% for transaction fees and management of the group buy.


(Thanks to TheSwede75 and SilentSonicBoom for their similar group buy that I used as a template for my group buy)

german government decided that no taxes have to be paid on gains of bitcoin prize rising (speculation) if the bitcoins are held for a 12 months period. that is much softer as on stockmarket gains! the german government gives bitcoin speculators an edge over traditional stockmarket speculators.

39  Alternate cryptocurrencies / Altcoin Discussion / dilemna with ripple - i just don't get it on: May 30, 2013, 09:39:55 PM
i am finding it hard to comprehend how Ripple will gain value
ok so
if each ripple is essentially just a transaction, why is the price so high?
there are 100 billion ripples which is basically 100 billion transactions, why do people think that this is a limited amount of ripples which will increase in value when
 liberty reserve has only done 55 million transactions in its lifespan

it doesn't make sense unless people actually think that on average the whole population of the human race will end up doing just under 20 transaction each

to invest in ripple is pretty much betting that everyone will use it, everyone

so why is the ripple price going up?
