Hello,

I'm just planning to start mining and trying to do the maths before it.
While I was trying to figure out my future profit, I realized that I use
a few assumptions that are not necessarily true.  Two of them:

1) I've measured that with X Mhash/s speed I earn Y BTC/week.  Now
I'm not sure that if I can double, tripple, etc. my speed, then my
earnings will double, trippe, etc. of Y.  Is that true, that if I would
have been mining with k*X speed, k*Y BTC have been earned?

2) When difficulty doubles, half as many BTC can be mined.

Well, these are the basics of my calculations, but I'm not sure of them.
I would like to know your opinion on the above two points.

Google tells me that 1 BTC is 0.0325 USD.

(...and it's called "Thai baht", not "BitCoin"...  )

Hi there,

I've just watched a presentation on youtube about data mining
the BitCoin block chain.  The presenter said that it is possible to
build up a graph that shows transactions between people.  I was
wandering if it is really possible, because AFAIK every time I send
bitcoins, the standard client uses a shiny new address. Please correct
me if I'm wrong, but the block chain contains only address->address
relations as the coins go from one address to another.  If source
addresses are always replaced with a new one after every transaction
(what's more, I can use as many addresses as receiver addresses as
I want), this graph will only show two type of figures:  single lines
between two points without any other relationships with other addresses,
and "stars", I mean single addresses, that receive money from more
than one addresses, but the senders won't have any other connections,
and the destination address will never appear in a transaction where
it is the source address.  Am I right?  Or do I missed something here?

Is there any other info in the blockchain that can be used?  There must
be the source address, the destination address and the amount.  Maybe
the transaction fee, but what else?


PS:  okay, maybe there's one case when an address can be a source
and a destination too.  When someone starts up a new wallet, and it
contains a default address, and s/he sends this address to others to
receive money.  Maybe in this case it is possible that the client will
lates use this address as a source address when the owner of the
wallet does her first outgoing transaction.

Hi there,

I have a couple of NCIPHER nFast 800 SSL accelerator cards here, and I would like to know if this is able to speed up somehow any kind of mining (cpu or others).  I know it's not a widely used piece of hw, so probably there's no ready-to-use miner for this at this time, but hopefully someone can tell me if I can use them for mining.  (If not: does somebody have any idea what is it good for then?)
