Haven't got any myself and feel that I've missed the boat, even after the value has dropped to ?250 or thereabouts... I'll probably read this in a couple of years and kick myself...


I have read repeated advice that you should store your bitcoins/wallet offline on a portable drive, rather than on your desktop device.

That's not strictly true - Bitcoin has infinite divisibility but the smallest denomination is a "satoshi" (0.00000001 BTC). That's the smallest amount that can be handled in a transaction.


8 decimal places is the smallest you can go for a transaction but apparently software can be modified to handle smaller amounts: https://en.bitcoin.it/wiki/FAQ


I guess it's a bit like the penny - fractions of pennies are possible (e.g. interest/loan repayments) but the bank wont let you withdraw or make transactions with anything lower than one.


My partner has Bitcoin and I've been looking into buying, just as an experiment really.

Wasn't there somebody recently who had done that, but mistakenly thrown it away, thereby depriving himself of the millions of pounds stored within it?

In the same way that all money is infinitely divisible...just like you can infinitely divide a penny or any other form of currency...!?


"Money is infinitely divisible in the sense that it is based upon the real number system. "


http://en.m.wikipedia.org/wiki/Infinite_divisibility


However as I said previously, there is a minimum denomination required for transactions (usually a 'satoshi' although apparently transactionsmof smaller amounts are possible). The fact that machines aren't able to calculate massively divided numbers is another matter.


And there are plenty of places to spend, buy or trade them. The market is extremely volatile and crashes happen frequently.

The time to speculate was in the past on this one. It's not transparent (shadowy founder), the Chinese Government have just banned conversion to RMB within China, and the volatility is horrendous.


Save your cash for the next virtual currency like Litecoin or NameCoin.


Lastly, if you see a gravy train, it's usually too late to board...

I was taking issue with the practical realities of infinite.


It's all fine to say that mathematically


def div_by_two(x)

x /= 2

div_by_two(x)


is possible.


In the real world you'll end up stuck at an atom surely?


In terms of systems being able to express that, you'll soon run out of digits on the right side of the dot, (or more likley throw a max recursion error in the above case).

Given that it is a currency that exists only within the electronic sphere it has to be limited by the physical limitation of the bits in the register surely?


Admittedly our prices are supplied at up to 24 dp which I always thought a little bit ott.


Oh god, I bored myself writing that...

That's true of any currency, but it doesn't mean it's not infinitely divisible.


Of course, you can come to a point of precision in any transaction that becomes useless because at very very small amounts the cost required to calculate the amount would outstrip any value gained from calculating it.


Anyway, point is yes you can get change from a bitcoin and you can even get change from 0.00000001 BTC if you want to hack together a system together to give it to you.

    • Dear Tessa Jowell GP Surgery, I write as once again I have experienced poor levels of patient service with the GP practice. On the Monday 3rd March I completed two online forms on your online platform. One was regarding pain following a ankle operation and the second request, was for a sick note: My pain was addressed by a telephone call at the end of the week by a GP.   I received a call from a clinical member of staff today regarding my sickness certificate. In the call, I was asked what can the surgery help me with? I informed the clinical staff member, I had no idea why the GP surgery was contacting me. The clinical staff member informed me, she was contacting me because of a sick note I requested for my employer on 3rd March 2025. I informed the staff member, today was 10th March, and I requested the sick note on 3rd March. I asked why I was being provided with a telephone appointment now? The member of staff informed me, this was due to clinical need. Its appalling, I have had to wait until the following week, for a clinical staff member to contact me, about a sick note for my employer. My employers policy, is similar to most, I am expected to present a sickness certificate to my employer to cover all absentness for sickness (except for the first 7 days of which I can self certificate). The delay in someone contacting me as led to me breaking my employers sick policy. This is totally unacceptable. This is not the first time I have been placed in this position, as it took several days for the previous sick note to be administered by a GP, which again my employer was not happy about. Infect, my employer reminded me, this was not the first or second occassion I had delayed submitting a sick certificate. I did ask the clinical staff member, why there was a delay in sending me the sick certificate, and I was advised, I needed to infrom my employer to refer me to their Occupational Health Service. I am not happy of the continued delayed services being provided by the surgery. You will see below, I have complained on a number of occasions, and you will see the surgery has a unwritten policy of not replying to complaints by email. The first entry in the email below dates February 2024, which mainly includes appointment slots, and non clinical issues. Despite assurances, things will improve in 2024, There is still issues with this surgery. In my last complaint on 3rd December 2024 there was no response from the surgery. Can you please explain why I have had to wait for someone to contact me today, despite a responsibility for employees to provide a sick certificate to their employer, straight after the previous sick certificate expires? There does not seem to be sufficient clinical staff to cater for the amount of patients registered at the surgery. This appeared to happen throughout 2024, and now in 2025. I must of been expecting a delay in administering a new sickness certificate as I completed one of your online forms as below, I was advised by a different Doctor, I could not request a new certificate, while a current certificate was in place. Based on my experiences, how can I ensure, if I need a medical certificate because i am unable to work, what should I should do differently? also, what is the surgery going to do to ensure I am not in a position like this again? Last week, my sickness could of been viewed as unauthorized as I had not complied with the sick staff policy once again. I have been nursing a painful ankle, following a operation. I should not endure additional stresses from the GP practice, on top of feeling very unwell. I was told during the call, a certificate would be provided until the end of the month, however, I have no idea how to access that certificate, and if the certificate would cover from todays date, or from the date requested. Despite assurances, of a better service from 2024, there still seems to be problems at the surgery, and I don't really see non clinical issues not being resolved. I am also still waiting for information regarding the next Patient participation Group meeting no information has been provided as yet, despite three online forms being completed, and assurances in summer 2024, this information would be presented to me. I have now asked for the Parliamentary & Health Ombudsman to make contact with me, as I have seen very little progress and have included the Care quality Commission into this email for the first time. I am very much exacerbated with the service being delivered by Tessa Jowell, and would welcome massive positive changes for the surgery. I know you usually do not respond to complaints, however, I would be grateful if you can replay to this email. Regards
