thanks, sorry for the dummy question...

Hi, please where can I asses the mastercoins I own? I sent in time to the exodus address?

However the greasemonkey script fails to tell me anything valid (but '0')

expecting a positive return in fiat is irrelevant to me.
bitcoin mining may be the only activity to analyze only in terms of bitcoin, without reference to fiat at all.

you spend some bitcoin for hardware at T0. You start mining at T1. You must plan full bitcoin break-even in at most 3 month time after T1, otherwise, you're likely to have lost your money.

Agreed. I cannot think of the current situation in words different than a bubble. However, what happens is that people waiting for asic *will* put them to work. So considering the current level of demand, the difficulty will continue to jump for a while.

I have improved my estimation using the current next difficulty estimate (78% increase, not 100%). The price to reasonably pay for a miner is in mBTC. This price involves one month delivery security (yes - optimistic) and one month insurance against huge difficulty increase

quoting pyramining: "Investing in Pyramining is indeed very profitable: the complete reward is estimated to be reached in less than 43 months."

To me, this is definitively a scam. Pay first, get your money back in 43!!! months :-)

except that the market is 4 times too expensive (considering the 3$/Gh january offer), and that soon people will start understanding this. So if the value of a BTC does not change, the price of the mining equipment must.

ok, you're right.
Unless the complete asic design/fabrication costs more than we can imagine.

At current BTC price and prepaid mining equipment cost, no offer on the market is viable. So crowdfunding should stop.

sure, lots of money went in smoke here.

an answer here:

at current mtgox price 139$, you should not pay now more than
16 dollars/GH if you expect mid october delivery
11 dollars/GH if you expect early november delivery
8 dollars/GH if you expect mid november delivery
6 dollars/GH if you expect early december delivery
4 dollars/GH if you expect mid december delivery
3 dollars/GH if you expect early january 2014 delivery

this is for raw break even. If you want to be on the safe side, these figures should be divided by four (one month delay, plus targetting to double your BTC)

or the value of a BTC should be multiplied by 4.

Deciding to mine is an important matter, also because this is a contribution to the network stability. How much can one decide to risk in this anyway?. I decided to share my analysis of the situation here (sorry, I don't know if such a self linking is ok with the TOU):

http://laurent.henocque.com/post/2013/09/16/On-Bitcoin-Mining-and-the-vallue-of-Bitcoin

My conclusion is that to account for risks, the value of a BTC is grossly fourfold underestimated. The reason is that to mine, one must expect obtaining more BTC (not $) than by buying them now.

BTC break even can be theoretically expected using mining hardware paid today (assuming 139$/BTC - but bitstamp rates make it worse) at:
    16 dollars/GH if you expect mid october delivery
    11 dollars/GH if you expect early november delivery
    8 dollars/GH if you expect mid november delivery
    6 dollars/GH if you expect early december delivery
    4 dollars/GH if you expect mid december delivery
    3 dollars/GH if you expect early january 2014 delivery
    ...

However, if you look at the table, the correct figures are in BTC
 
To be on a 'safe' side should mean to at least anticipate a one month late delivery, and to expect doubling the BTC. So 3$ / Gh paid today for a delivery in january is not good. I would not accept to pay more than 0.7 $ for this.

More badly, a KNCMiner Saturn expected 'sometime in October, or November' will never mine the BTC it cost (from June to now).

I may be wrong indeed...

Sometimes the best way to trigger adoption is to forbid usage.
The french kingdom and Parmentier did the same to foster adoption of potatoes. They claimed it was private to the court, used military guards in the day to keep the fields but they  leaked recipes...

achète un bitcoin, tu ne le regretteras pas.
et garde le sur le wallet de ton site d'échange, ou alors sur blockchain.

when people sell mass amounts, this drives the market downwards,
when others want to buy large amounts, they should accept to take the market upwards.
this is fair

ok, now, I have to figure out what all this really means...
@Tradefortress, if you really have a 1 trillion btc balance (-278...), does that mean that if someone trusts you for 21 million, you may send 21 million btc
That can later be distributed to more trusting people?

How could you manage to achieve the trillion btc balance?

thanks Azrael, you helped me get unlocked. I'll reciprocate.

rpkDcgsFcnEhvP2XV8Zo2AvQEdUwk7TYfe

ok for me. thinks don't work at all for me for the moment.
and I discovered that in ripple economy 50 == 0
I'm curious to see further details of this, while spending my newbie time.

rpkDcgsFcnEhvP2XV8Zo2AvQEdUwk7TYfe

ok, and did you do it twice? I got 50 (now 49.999999...) from a first send, no second one.

(edit) however, from your screen capture, i see that you have a different 'sent to' address.
This is not rpkDcgsFcnEhvP2XV8Zo2AvQEdUwk7TYfe

Thanks again Azrael, however this does not show up. Did you use rpkDcgsFcnEhvP2XV8Zo2AvQEdUwk7TYfe?
