Unexpectedly, despite a ROI 4 times higher than S&P500 since the beginning of the year, the Sharpe ratio of BTC is only a little bit lower than the S&P500 one.
It means BTC isn't disproportionately risky for such a ROI.

The Sharpe ratio was developed by Nobel laureate William F. Sharpe and is used to help investors understand the return of an investment compared to its risk. The ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk.
Subtracting the risk-free rate from the mean return allows an investor to better isolate the profits associated with risk-taking activities. Generally, the greater the value of the Sharpe ratio, the more attractive the risk-adjusted return.​

Risk Free Rate for USD is a joke, isn't it?

Lots of risks holding long that asset being under central dilution powers

For that price, customers do not get the display – which starts at $4,999 – or the $999 stand that holds up that screen.

Wow, that's over 7 BTC.

We know u can all buy such studies... best industries found guilty are pharma and finance

I have a bit of a problem with that Yale study (from mid-2018), and its seeming lack of ability to focus itself on bitcoin, and has this strange concept of "cryptocurrency" that dilutes the message of king daddy by the addition of confusing matters such as Ripple and Ethereum to such cryptocurrency conceptualization.

Makes for a weaker study to not just focus on bitcoin, so it seems.

That too.

explain

Micro$oft end of support for Win7 eminent.

Handy to have internet in the shop for looking up specs, constants, formulas and whatnot.  No room or patience for 2 machines out there.

Antique CNC controller (Super-Tech EMC-XYZ-BX) has no drivers or config info for Linux, figured this out after 3 different distro installs.

Turns out, Mach3 parallel port driver absolutely will not work in a 64bit environment, figured this out after setting up a salvaged machine with win10 already on it.

Started to re-purpose another older box, kept hanging on install, several hours to track that down to a flaky CPU, have to do a win7 install first because this thing won't boot from USB, finally get that all worked out and...

now having to sidestep Micro$oft account creation and muzzle Cortana and turn off all the spylemetry (that they let you), so far it has been 3 days of walking in place and I don't even know if this is going to driver up its PCI-parallel card and work yet


and being reminded that I have to go through Linux dependency hell on all the rest of the boxen by Jan 14...

Ever tried virtualisation?
VMware did a pretty good job at running 32 bit OS like WinXP in a window, while passing through USB hardware from the host OS (win10 64bit).
So if mach3 is running on a decent USB-PPT interface, i'd check that too.
I have run my car's OBD stonage interface via USBCOM serial port-USB bridge controller under such configurations successfully.

Well worth a try, imo. And oracle's virtualbox should do it sufficiently, too (for free).

EDIT: I googled "usb parallel port mach 3" and judging by the first three results it shouldn't be much of a problem to get things running that way.

That list could not be complete (which you said).  Missing the largest one (or most scandalous one of 2019), Quadrigacx, no?  And of course there is BTC-e and WEX in 2017/2018.

Edit.  Xhomerx10 beat me, partly.

I will gladly beat the parts he missed.

EDIT: gladly

The problem is latency.

CNC needs really precise timing, like realtime kernel precise, which is why the parallel port is on the PCI bus, USB adapters are a recipe for disaster. 

I know you googled, but those hits are referring to purpose built USB input motion controllers that deal with timing internally.  This thing isn't worth converting to a new motion controller...though somehow it is worth days of my time...

[Arriemoller]

I know absolutely nothing about computers, but if your problem is that your old machine isn't compatible with a new computer, why don't you just buy an old computer on Ebay?

Hmm, i see.
Perle adapters (parallel over ethernet) might be another option, but i never tried that, i just read somewhere that these are quite timing-accurate.
Having a quick look into "pci passthru", that means passing a pci device to a virtual machine guest OS, is only supported in VirtualBox Linux version and VMWare ESX (which replaces the host OS, win10x64 in this case, to allow device level passthru). If i am interpreting the information correctly, it's a windows license thing that passthru isnt supported in windoze. These stupid redmont fuckers :/

If you really hang to it, i'd get an old win32 micro-atx box or laptop with built-in PPT and no internet access, using an old KVM switch to save space and share one set of keyboard, mouse and monitor between the two computers. I used to work like this with three local servers and a workstation in development and it was quite convenient, also because i didn't have to stay in the noisy server room next door. Just drilled a hole for the cables through the wall.

AFAIR, he doesn't have enough space for two boxes.

Downtrend channel seems to hold. Filthy grinding to the future bottom. Hail to the halving

I just teamed up with jbreher and wrote a self-help book on the topic.




(Note:  That is NOT me (nor jbreher - apparently?), so don't go hating on that fellow)

I was always friendly to my haters. It saves you from troubles with the stomach by reducing anger and it gives that unbeatable feeling of staying on top. Like parents, when a kid is freaking out. It sends a subtle message of predominance to your opponent.

[Arriemoller]

I'd rather beat him up, that feeling is quite nice too.

Hey - looooong time lurker ..... longer time holder. Think this may be my first time posting.

Long time interested in earning interest. To date, all methods of doing that just seemed like a good way to lose whatever coin I elected to lend.

However, been looking at blockfi lately.

Anyone have any experience with it?

Paying interest in bitcoins is a very simple play. Scammers will get your bitcoins with pleasure and sell them for fiat at the very moment they get them. They will even pay you interest if bitcoin price goes down and will show you the middle finger if price goes up. This is why only retards are looking for places where they can deposit their bitcoins to earn interest!

Thanks for reminding me why I don't post.

Appreciate the link psycodad - will be interested to see your experience.

Yeah.. don't let one bad apple spoil the bunch... I think your question is good and interesting.  And businesses like BlockFi are certainly in the future for Bitcoin.  But custody is still not entirely a solved problem. 

All the issues with bitcoin custody can be easily solved. More regulations to protect customers are needed...

Every retard that is looking to deposit their bitcoins to 'earn' interest is sponsoring bitcoin dumps. It is really that simple!

[cAPSLOCK]

Mine came out to over $11k :|

Woof.  With the new hash algorithm you might make a little scratch mining Monero in your downtime with that thing.

In the office? At the meeting?
Nice to dream about that, but in RL this never was an option.
I had bad luck with violence from the start, so i avoided it. In school, two guys were mobbing me, so i hit one guy with the back of my hand full-on and his nose started to bleed like mad. Then the teacher made sure i was kicked out of school. Lesson learned (but i never mobbed anyone, later on).

Damn, I’m bored..... WO is boring, btc is boring, time to see a nobrainer serie “slasher”

Sometimes I do like those series especially when I’m tired AF

Btw, WO could use some magical x-mass dust
