1  Other / MultiBit / Re: Trouble Exporting from Multibit Classic to Electrum on: September 23, 2017, 06:44:55 AM
Hi
I have read forums and advice from exporting private keys to Electrum.

I have Multibit Classic wallet that was stored on USB.  I generated a private key that I tried to import into Electrum but shows 0 BTC after it was done??

I must be doing something wrong.  Would appreciate any advice.

Cheers
B

Did you let it load properly?

Hi,

Just posting a message to say, I am one of the people who pre ordered and didn't receive anything.

I don't know how all of this works, but if people here want to launch legal action or whatever, I am available to help if there is a way (signing stuff, sending testimony, or I can also help a bit with fees).

I think if everyone agrees to place a grouped complaint or something, by grouping money for attorneys and other stuff this is doable. No?

What about taking legal action?

I don't know much about it, but maybe there is a way to associate with each other to launch a legal action asking for our refund? I am not american but if anyone is from the same state or at least the continent, I suppose this is doable?

If anyone is interested by that we could put in place a private website/forum/whatever to organize that.

Just a post to say I made a little update : Now the website display shareable URLs, so you can directly link a category/search/whatever to someone.

Thanks, this is cool!

I suggest an option to edit a store once posted. I guess that'd need a password system...

Yeah, I was doing too many things at once and messed up my entry a bit. Cheesy

I actually already developped the edit system, but didn't put it online because I'm affraid people will replace links, or things like that. I don't know how to enable it in a non-dangerous way.

Maybe putting edits on a "pending" status that I would have to verify, but I don't like this solution.

Anyway if you need to edit an entry you can mail/pm me, as explained in the about section

Thanks for adding All Things Luxury to the list, we also sell silver bullion along with Jewelry products. We are introducing a line of authentic diamond engagement rings this month. We have a few already online and are finding huge demand from the bitcoin community. Thanks!

You're quite welcome Smiley

What methods do you use to keep scammers at bay?

Are there any volunteers checking the list or does it have some kind of upvote system?

the initial reason I built this website is to keep scammers at bay. There is a popularity bar on each websites, and people can like/dislike (only once per IP of course). There is also a comment page for each store.

Then if something is reported as a scam I will delete it.

I also plan on adding some features related to these matters like:
* A suspsicious flag that would appear after a certain dislike threshold
* Evaluations (with 5 stars and stuff)

But of course I can't check manually every added stores.

Edit: People can see the public todo-list and vote/comment stuff

Being able to add a physical location or add in a country and region during the submission might help.

You could quickly get swamped with sites, this might help people find things.

For example, people in the US will not be interested in physical stores or items from the UK, in most cases.

K

That's on my plan, but most of the stores added for now are virtual stores that ship internationally.

I want to add this feature so people can add physical stores/places that accept bitcoin with their address, and then later I can generate a map showing stores arround the user.

Yay, categories!

Minor bug: (in chrome) category list goes past the bottom of the page, no way to scroll it

Yes if you have a small screen it happens... I'm not sure how to fix this though. There is just too much categories... But yea I noticed that. If anyone has a good idea about that I'd like to hear it

Edit: Never mind, I found a way to add a scrollbar to it.
10  Bitcoin / Project Development / Re: Community-run list of Bitcoin merchants (help me fill it!) on: December 07, 2013, 02:24:28 PM
That's a pretty good idea, but that means I should add the possibility to add physical stores with their location. Why not...
11  Bitcoin / Project Development / Re: Community-run list of Bitcoin merchants (help me fill it!) on: December 05, 2013, 04:06:50 PM
The website has been updated with support for categories, markdown for people to write nice presentation pages and multi keyword searching Smiley
12  Bitcoin / Project Development / Re: Community-run list of Bitcoin merchants (help me fill it!) on: December 04, 2013, 06:46:27 PM
When I want to buy something with bitcoin, I usually know what kind of thing I'm looking for and then try to find a bitcoin-accepting vendor. What about categories, or a way to browse the keywords? A tagcloud-style keyword index could be cool...

Yep that's the next things I will add to the website. Tag generation and categories are already in the database, they're just not browsable yet.

Thanks for the feedback !

Hi Smiley
bitcoinrep.org is a community list of all website that accept bitcoins as a payment method.
It is designed to provide an easy to access list of ways for people to use their bitcoins.
Community features such as likes/dislikes and comments are here to help people see which websites are popular and trustable.

I don't know about you here, but most of the time when I'm looking for an easy to use and complete list of merchants that accept bitcoins, it gets complicated. This is why I made this website. The goal is for everyone to be able to find what they are looking for, easily.

I always wanted to do something for the bitcoin community, so here I am, this website is my contribution.

What it features:
  • Community list of bitcoin merchants. Users can add new merchants
  • Likes, Dislikes and comment features so people can know which merchants are trustable
  • Searching by keywords
  • Clean design: No ads or boring stuff that gets in the way, just the websites
  • Fully responsive

Hope you'll like it. And please don't hesitate to add new websites to the list and/or give feedback

get GPU so when you cant mine you can sell them

Can GPU break even in mining ? I remember GPU not being very efficient, which is probably even more the case now, considering they're made for 3D apps and not only mining. Plus you have to power the motherboard/processor/hard drive to mine...
15  Other / Beginners & Help / Re: Investing on the Prospero mining rig on: October 20, 2013, 06:12:52 PM
Well the difficulty shall breach the 1 000 000 000 barrier by them, I think.
Even though the price is very good, take this in consideration.

Well you made me think of running the calculator on future possible difficulty levels. Here are the results :

1 000 000 000 8.64 a day, break even in 37 days - At this point, it is actually pretty nice
2 000 000 000 4.12 a day, break even in 77 days - At this point it seems reasonably good to me
3 000 000 000 2.68 a day, break even in 122 days - At this point I think it is a bad/useless investment.

Considering the fact that bitcoin value is always getting up, my calculations are based on $170/BTC but they will probably be actually more valuable in february.

This makes me pretty confident on this investment. I personally think (well, hope) that the difficulty won't keep this pace it has had these last months, but even if it does, there is still a pretty good margin of profitability Cheesy

This will actually be my first time with mining (well, except a few days back when btcs were worth $10) I'm curious how much it will actually earn
17  Other / Beginners & Help / Investing on the Prospero mining rig on: October 20, 2013, 03:30:46 PM
Hey guys Smiley

I just purchased  (pre-ordered actually) the Propspero mining rig.

It is hugely better than any current mining rig on the market.
It offers arround 100 GH/s for ~$300 (including shipping fees and stuff) which is just awesome. Its efficiency is close to 300, which is ~10/20 times better than the efficiency of most of the mining rig at this sort of price (less than $500).

Based on the current difficulty, it would earn $31/day (see screenshot from the bitcoin mining calculator), breaking even in only 10 days.

So of course that is just great. But the big downside is this :
  • It ships on feb 2014, so arround 4 months from now.
  • I'm wondering how you can multiply by 10 the power of mining rigs in only 4 months. Are they actually able to build this powerful and cheap rig ?
  • By then the difficulty can improve, and that's where all the danger is.
As you may know, bitcoin difficulty has hugely accelerated these last months, but can we say it will keep accelerating this way ?

Well I don't think so.

Everyone has heard about Moore's law that basically says that computing power doubles every two years. Well according to this law, our computer's processing speeds needs two years to double, so how come so much bitcoin difficulty increase in a short period of time ?

My answer is popularity. Given all the big events around bitcoins this year, bitcoin has become hot. Everyone wants to give it a try and so the number of mining computers (the number, not their power !) has dramatically increased.
Now I hear many people who start thinking that bitcoin mining is not a thing anymore precisely because of this enormous increasing in difficulty. While everyone rushed at bitcoin mining, the difficulty just adapted to the number of people using bitcoins.

Will this trend continue for a long time ? Probably not. And if this trend stops, the accelerating curve of the difficulty will stop with it. The big question is : Will it stop soon enough so the Prospero mining rig can be profitable or not ? I think there is a chance it does.

Now my last concern is about the actual possibility of shipping this powerful rig in 4 months. It seems a little bit unbelievable compared to what's currently on the market... But the company has a past of happy customers. I checked this thread where they present it. While there is a lot of scepticism, every past customers who posted on this long thread seemed extremely happy about their product. Of course they can make false accounts, but most of them were old accounts with lots of messages, and there was a lot of posts. So I think they are actually trustable.

What do you think of it ? Did anyone pre order it ?
