Heh, I've just bought some corn. At the perfect 55k. I'm starting to understand the rules of this game.

If it goes a lot below 55k, I'll make sure to to re-read the manual. And to buy more.

BTW it feels sooo funny that just by listening to WO regulars for the last four years i turned from panicking on every little daily dip to embracing, even enjoying dumps like 5% or more. If i wouldn't have done this, i would probably have gotten out at some bottom and got burned like mind.... you know who.

Long time we saw that bones guy not ?

Then get us back around 60 

He was right again! https://www.youtube.com/watch?v=XbZ8zDpX2Mg

Calm down, we're at support now. The massive green weekend candle was crying for a dip like this. Some people don't get their greedy mouths full enough of worthless fiat (or shitcoins). Honey badger moving on.

#BTFD

I'd do like this: Buy the dip with half of what you want to put in, wait for a second one to spend the rest.
#nofinancialadvice

Just in time for all those stimulus checks to be sent to exchanges.

Some very aggressive dumping going on here

Dump

It may be just me, but i think the weekly dump at the start of the week in european timezones became quite a regular occurrence.
(EDIT: especially after pumpy weekends)
Could be related.

EDIT: I had a funny lil talk yesterday, with a guy that started saving (fonds) for bulding a home two years ago, when i asked him to look into bitcoin.
Back then, he said: "Bitcoin is over, $20k was the top of the bubble..." and of course he brought the popular "too late to invest in BTC" argument.
So i asked him yesterday if he bought.
He replkied: "You know, i am doing this fonds savings stuff and i'm satisfied with the 19% i get out of it per year."
And then, what was the jawdropper of the year for me: "I heard Bitcoin did well too, afaik it shows about the same performance". 
I didn't know what to say. Things like "you know, you could have financed several houses until date with the help of Bitcoin AND set the tracks for early retirement", but i didn't want to blame a (humble and friendly) nocoiner. I can't imagine the pain if he decided to look at the charts later.

You folks are scaring me.


1 BTC = 1 BTC.  Ah, what a relief.

(The dollar got a bump up to 1720 sats; but the bubble can’t hold.  Yawn.)

Don't worry, the pump will come. The brrrr of the money machine is pretty loud and I don't think that the bears want to lose money, so they'll have to take a break pretty soon.


PS. I also thought that this Monday will start with a pump, but let's not forget that in America is not morning yet 

Thanks for the merit, serveria.com, but my above post didn't age well.

No worries, next week things will be totally different, as we all know...

And the next tweet:


I remember I read somewhere that Pi to an accuracy of only 5 decimal places is sufficient for practical orbital calculations up to the scale of our solar system. Given that, I'd risk a guess that the approximation of Pi that I get using Windows 10 calculator (3.1415926535897932384626433832795) should be sufficient for Dyson Sphere calculations. But I'm not a physicist.

Anyone who has ever lost data due to a failed storage device would attest to that. I've set up my main PC to take daily backups to a device in a different physical location. Funny thing is that, since I started doing this, I haven't had a single device failure... Murphy's Law?

Yeah, price really going down yo!

We appear to be headed below the previous ATH, which is a new occurrence in this bull run

JJG, please stop.
Speaking that, baby talk. Now.
Many still like you.

But if you still rage
At peeps that you don't like,  then
One more, SIM attack?

Tell us what you said,
Tell us where you leaked info.
How much did you lose?

If I, searched for me?
I mostly see, bitcointalk.
Maybe change your name.

Why do you think that you know anything about my situation?
It all a bunch of baby-talk gobbledygook.
You try to read too much into people and it is misfiring 100%, at least in my case.

That’s true, and it’s an interesting observation; but how does hashing help?  Some handwavy scheme to produce pseudorandom numbers faster than your CPU can process them?  ;-)

GPUs can’t be used to mine Bitcoin.  It’s so infeasible that discussion of GPU mining is banned from the Bitcoin mining forum, per the stickied rules thread there:


I have seen some colourable claims that high-end FPGAs can still meaningfully mine Bitcoin.  I do not know whether or not that is true; either way, that would be ridiculously expensive compared to buying an ASIC.


It is indeed astounding.  And that is what secures the network against double-spends!  To do a so-called “51% attack”, you need to do more computation than everybody else combined (so that you are doing more than half the total, and everybody else is doing less than half).  (N.b. that even a 51% attacker can only double-spend, and censor transactions.  Even a 51% attacker cannot spend arbitrary coins owned by other people, or otherwise violate consensus rules.)


I should note, GPUs are not necessarily faster than CPUs.  They are faster than CPUs for very specific types of operations:  Roughly speaking, tight loops that can be run in parallel.  The core speed of a typical GPU is actually slower than that of a typical high-end CPU!  But GPUs do a whole bunch of the same thing at once more slowly, instead of doing one thing at a time more quickly.  (That’s the most nontechnical way that I can explain it.)

I am not very much familiar with pi algorithms.  I don’t know how well they parallelize.  I do know that they typically require huge amounts of fast storage, as I have repeatedly mentioned.  If the algorithm can’t be parallelized, then a CPU will be faster than a GPU.  If it’s I/O bound, then the question is irrelevant because your processor wastes time waiting for your storage media.  Same as for memory bandwidth (another big issue in high-performance computing).

GPUs beat CPUs at Bitcoin mining because Bitcoin mining is what’s called “embarrassingly parallel”:  The algorithm is so easy to parallelize that it’s almost as if it was designed for that.  Games use GPUs because many different graphics rendering algorithms (especially 3D) are embarrassingly parallel.  AI also does a huge amount of parallel stuff.  Anything single-threaded will run much faster on a CPU.  That is essentially why we have CPUs, and don’t just redesign GPUs to run all of our programs.  Most types of general-purpose computing run best on a CPU; a few types of computing run much, much better on a GPU.  Different tools for different jobs.


Not sure what you mean.  I think that your terminology is off.

Anyway, however many digits you mean:  How do you intend to store all of these digits?  Really, really biiiiig disks?
