Thank you for that useful information. I have been in sales for a good while now, but I am new to these forums. I still need to learn the escrow thing, but I do have a coinbase wallet which is very trustworthy. I will make up ads for some of the more popular units, I just have so many available I didn't want to flood forums. Thank you again.

Escrow here is fairly simple.

Buyer selects an escrow agent usually from here:
https://bitcointalk.org/index.php?topic=276897.0

https://bitcointalk.org/index.php?topic=2439910.0

These steps might vary a bit depending on who you use.

You and the buyer agree on the escrow agent and create a PM asking the escrow agent to escrow your deal.

Including What is being purchased, pricing any other information on the deal (tracking etc.)

The buyer sends the escrow agent the agreed upon funds + the escrow fee.

You ship the item to the buyer, and provide the tracking information to the buyer and escrow agent.

Item arrives to the buyer and the buyer replies to you and the escrow agent asking to release the funds.

Escrow agent releases funds.

Your management is really doing a very shitty job.



Time to fire your management and lock this thread till you fix the issues.
How are they supposed to pay for it and put content on the site if no one buys the "privilege" to post articles on the site?


lol...

@OP A decent host + registration is about $USD130 a year + about $15 for a commodo cert, and there are cheaper if you don't care about some control.

224  Bitcoin / Mining speculation / Re: Is 110V mining going away? on: April 19, 2019, 03:00:30 PM
Yes, the US is one of the few 110 places. I just happen to live here so...
220 in many locations is not as common as some people think. The condo I live in now is 110 only. Even in the entire community, Condos, town homes & full detached houses the master plan is all 110. It's happening more and more if you have gas for the dryer / oven / stove / etc. 220 was not needed. Actually a bit of an issue now with a lot of people getting electric cars and then dealing with pulling in 220 from the street.

I live there also, and yeah I know condos / apartments don't have it. My belief on this is fairly simple, the condo / apartment companies don't want any issues with dumb people mistakenly plugging in a device that isn't rated for 240 into a 240 plug. I've seen people forget to flip the 110 to 240 switch on a PSU and then plug it into a 240 outlet even after being told make sure x switch is set to 240.

I've seen the same thing with a 110v surge protector going into a 240 outlet. etc etc.

From a business owner / landlords perspective it's easier and safer to not give the option.

As for those small DC's, I still think they're dumb. As to what you can do, not host there and tell them your reason is they don't have 240v like most others. They either get on board with 240 or get left in the dust.
225  Bitcoin / Mining speculation / Re: Is 110V mining going away? on: April 19, 2019, 02:36:21 PM
We're getting to the point where mining just needs a bunch of power to run anything worth running. Yes there are some smaller less power hungry machines being made but those are more geared toward hobbiests(? spelling) while they might be similar in efficiency the hashrates make it so you barely earn anything. To get to a hashrate that you actually make a decent earning per machine you just need more power.

The US is one of a few countries that houses are for the most part just 110, and even then most houses have 220 installed (think your dryer), you can get more 220 breakers into your house by getting an electrician and having some rewiring done.

If a DC in the US isn't using 220 they are fairly dumb, power efficiency is usually better at the higher voltage and most electronics are ok up to 240.

227  Bitcoin / Mining support / Re: avalonminer 921 keeps restarting on: April 17, 2019, 01:44:39 PM
I've always suggested people to only use 2 or 3 per AUC3 chain, i.e. 8-12 miners per RPi so that stales don't get too high
More stales means more lost shares and more possible lost blocks.
I'm not sure how bad this is with the A921, but certainly was necessary with the A7 and A8
YMMV

If you can't find a cable problem, get another RPi for half of them.

Weird, I have more than the recommended amount and am under 1% bad shares. When I didn't set a custom difficulty for the pool this was much higher.

Very often chains of 4 and 5 fail and reboot.

I have more than this and only have seen 1 AUC cycle, it was a bad AUC it didn't work with just 1 miner on it.
228  Bitcoin / Mining support / Re: avalonminer 921 keeps restarting on: April 16, 2019, 06:14:14 PM
He doesn't need to do all this work if he knows it's always the same chain, he can flip on the led to find the chain that keeps going, then use the known good chain to check the usb port.

We had one pi that would keep dropping the chain it would usually get up to AUC# 8 within 24 hours, quick swap of the AUC and it never did that again.

These instructions would be to try and locate a bad i2c cable, which it is possible to have a bad one but based on what he's said and posted if it was a bad i2c cable it would likely be the one connected to the AUC.
229  Bitcoin / Mining support / Re: avalonminer 921 keeps restarting on: April 16, 2019, 04:15:31 PM
Try one chain at a time in each USB port on the pi, it's possible the pi has a bad port.

If none of the ports are bad then check each AUC, we had a bad AUC once that would keep restarting.

I mean have you tried contacting the owner with the privacy guard proxy? Isn't that how that works, you send an email to the registrant proxy and it gets forwarded to the actual registrant.
231  Bitcoin / Hardware / Re: April 4th, 2019 Canaan Low Power Mode on: April 15, 2019, 08:22:54 PM
Make sure your running the new April 04th 2019 firmware in LowPower mode.

I'm running the April version with custom settings, all the mode does is alter the same settings with the exception that you don't need to manually enter them. The best I was able to get efficiency wise on the April version was 102j/ths, in a previous version I believe it was February or January I was able to get 94j/ths on the same miners.

Now this is on the 851 which have been a bit less efficient then our 841's from the beginning.
232  Economy / Services / Re: ISO Good low cost sign printer that accepts BTC on: April 15, 2019, 05:46:22 PM
Trying to get some attention with some signs.  Been looking at signcheap and a few others...hoping someone here knows of a good printer that accepts BTC.

Thanks.
What kind of sign are you looking to get and quantity? Do you have an example and the design already made? The only other question would be where is it being shipped to.

I'll try to check on this thread but a PM would get a quicker reply from me.
233  Bitcoin / Hardware / Re: April 4th, 2019 Canaan Low Power Mode on: April 15, 2019, 04:41:35 PM
The best I was able to do on the 851 is 102, I was able to get 94 a few firmware versions ago.

I might be able to get better as I haven't gone to the lower limits of the frequencies yet.
234  Bitcoin / Mining support / Re: Antminer S9 March 4th, 2019 firmware experience? on: April 13, 2019, 03:46:56 PM
Are the controllers different models? If it doesn't like LPEM there might be a setting in enhanced mode that controller / sub model doesn't like.
235  Bitcoin / Pools / Re: [∞ YH] solo.ckpool.org 1% fee solo mining USA/DE 252 blocks solved! on: April 12, 2019, 07:36:35 PM
My mining info on my T9+ dashboard said I found 2 blocks. I would send a pic of the miner status if I could.
The page on the gui doesn't actually show what you've found, I forgot what this field meant. There should be a field called "Best Share" if that number is over the current BTC difficulty in theory you should have found a block, which as of now it would need to be over 6,393,023,717,202
236  Bitcoin / Mining support / Re: Antminer S9 March 4th, 2019 firmware experience? on: April 10, 2019, 02:47:54 PM
There is a simple yet effective way to by pass that stupid signature thing , you can follow my thread here > https://bitcointalk.org/index.php?topic=5090664.msg48938476#msg48938476

in case that does not work, copy  the code in this file

upgrade.cgi

post it here and i will alter the code so that it it will allow you to downgrade to any firmware you want.

This would be useful, but they also limited ssh ability so there is no way to ssh in to edit the file.
237  Economy / Services / Re: How To Accept Recurring Bitcoin Payments? on: April 09, 2019, 04:04:29 PM

Yes, i don't see why OP can't use something like Bitpay or coinpayments for a month to month subscription service.
Coinpayments; https://www.coinpayments.net/apidoc-accepting

If you have a bit of technical knowledge yourself, you can probably even cut the third-party out, and just use Bitcoin core. (Which will save some % on each tx.)

Two others that might be worth looking in to;
https://www.blockonomics.co/merchants#/page1
https://gourl.io


OP is looking for recurrent payment options not one time. As far as I know coinpayments and other offers one time payment only. Honestly speaking, I have never seen a recurrent payment using Bitcoin yet.
I think coinbase offered subscriptions some time ago not sure if they still do.

The issue with a subscription / reoccurring transaction and Bitcoin is the you don't pull BTC / crypto, the sender has to send it. If none of these services offer a subscription the best way to go about it would likely be to assign every user an address and run a script that checks for payment. Every month the user has to check to see what this months payment amount is and then send it to the same address, the script checks periodically to see if the subscription was paid up and continues to provide access to the service if it was or adds time to the account.

Otherwise if you use one of the other services, they are just acting in a similar manner to paypal or a credit card company where they will take x USD/BTC/LTC/etc. from the user and transfer it to you.
238  Bitcoin / Mining support / Re: Antminer S9 March 4th, 2019 firmware experience? on: April 09, 2019, 03:39:36 PM
So for a few hours you were able to SSH and then it went away?

Are you not able to revert firmware? or did they just remove the previous firmware from the site so you no longer have it?

If you reboot does SSH come back, as in is it a time lock? The S15 that I tested didn't have the capability to SSH in the released firmware, the code and programs to SSH were there just not enabled. Since we had no access to the systems we didn't go forward with more S15's and since the T15's were so similar never even thought of getting those. If this is the case it's possible they are trying to reduce the control users have over their own systems.
239  Bitcoin / Mining support / Re: Antminer S9 March 4th, 2019 firmware experience? on: April 09, 2019, 01:52:11 AM
This isn't any suggestion but more of a question on the other S9's. Does ssh work on the others?
240  Bitcoin / Project Development / Re: New Cryptocurrency Calculator on: April 08, 2019, 01:58:49 PM
Hi everyone!

We built a cryptocurrency calculator and we’re happy to share it with others.

Crypto.Calc ( https://cryptocalc.online/en) allows you to calculate your profit from mining. Just choose coin, fill form with your parameters and see results on right panel! Easy to make decisions what coin is more profitable for you!

Please, try it and let us know what you think! I will be grateful for the comments!
Love the layout and ease of use.

Looks good but mining calculators are deceiving . What I mean is that new people don't know that difficulty will keep rising especially when new hardware gets released.  They get a false sense of what their projected ROI is when its actually much longer.
I know I've seen a few places that had a more advanced mode, where you can do things like add x% per difficulty calculation. For this site it might be useful to have user entered / site prefilled based on expected difficulty. I don't remember the site I used previously but they listed the earnings and profit calculation in a per difficulty table when you put in the adjustment.

Some other suggestions.

Putting a link to the official manufactures site for purchase of the miners, or work with a reputable reseller and make a deal with them for  referrals. If you can't or don't want to do referrals I'd say at least the manufacturers main site.

In the coin details, a link to the coins main site, like bitcoin to bitcoin.org and another for discussion on this site/forum.

For conversions, also have a service for actually converting the coins. I do like how it calculates out an expected you will receive this amount. Services like shapeshift have api's that you can also integrate and get a commission off of.

Only other thing I can think of right now would be some type of api.
