thanks for staying on top of it guys.

any chance of selling our shares back if something isnt worked out soon?
You are more than welcome to sell your shares to someone else and have them transferred (after the spreadsheet maintenance is done) however the DZMC doesn't have a cash / BTC reserve to buy back / refund as soon as an order is placed it is paid for.

What does this mean on the OP?

Quote
Once sales begin, Refunds are available up until unit ships at 1.5% restock fee.

Maybe there was a misunderstanding then.

Yes sorry for the misunderstanding.

I think you misunderstood my variance acceptance limit. I'm OK with 0.013BTC/MH.  I am not OK with 0.003BTC/MH.  That is a HUGE difference.

I thought you meant that you weren't okay with the payout fluctuating by 0.003.  Big difference, yeah.

Adding a luck indicator to the pool stats would help a bit.

By the way poolwaffle check your PM. I sent you one but maybe you can't PM me back because you are a newbie. No need to reply on content here, just making sure you saw it.
13744  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN][POOL] Profit switching pool - wafflepool.com on: January 31, 2014, 04:42:55 AM
Switching the coins on/off wouldn't be needed, they'd be available to be mined all the time.  Its just that trades would be less frequent (so there is some price risk with holding for 12 hours or something).

Price risk is pretty bad on these coins. They could (and likely will) crash at any time.

The reason I suggest turning them off is there is usually going to be an almost-as-profitable coin the mine that won't incur the price risk. I guess you could program in some kind of profit threshold where you are willing to mine-and-hold (temporarily) if the profitability is sufficiently better.
13745  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN][POOL] Profit switching pool - wafflepool.com on: January 31, 2014, 04:28:18 AM
Its unfortunately not a matter of coinedup being a priority.  They literally don't have a trading API, which means that all the trades would need to be done manually.  I'm not completely against it if it means 2x profits, but it would open up a lot of risk.  Right now we're api trading nonstop as coins confirm, but with it being manual, the best we'd be able to do would be 2x a day or so.

You could switch it on and off when someone is available to manually trade them. Better than nothing.

If you're not willing to accept variance then you have no business on a 500 MH pool.  Just take a look at the pool hash rate and move on (until it gets bigger at least).



Wow, that's a bit arrogant. So are you going to start telling me how to live my life? Who are you trying to defend? I've said nothing but good things about waffle. Are you seriously white knighting a different pool in a thread about waffle?

God no, I love waffle. I said earlier in this thread I was in the process of building a switching pool that does the same thing.

I'm just saying that 500 MH pool is going to have a lot of variance, you were the one who said you couldn't accept that. It's unavoidable (other than growing the pool or offering something like PPS which is a whole other issue).

Also, I actually think there is more variance than is visible on that table because there are some very big payoffs on some of these coins that it is hard for a small pool to hit (but it will eventually/occasionally hit them, or it will hit them more if it gets bigger).

13747  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN][POOL] Profit switching pool - wafflepool.com on: January 31, 2014, 02:47:44 AM
Not at a variance level I'm willing to accept.  Time is required only when variance falls into a range I'm comfortable with. 0.003 BTC/MH is not an acceptable low end spike for me. It could be considered an outlier, but when two separate tests achieved the same low end spike on two different days it was not worth my effort to try again until other clients start reporting better stability.

If you're not willing to accept variance then you have no business on a 500 MH pool.  Just take a look at the pool hash rate and move on (until it gets bigger at least).

13748  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN][POOL] Profit switching pool - wafflepool.com on: January 31, 2014, 02:38:11 AM

hashcows has been paying me about .03BTC/mhashday. I think coinedup should be priority 1

Seriously? When did that start happening?

Well cows has been mining a lot of MEOW and MEOW has been hot so it isn't surprising that it adds to earnings. Luck is probably a factor too.
13749  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN][POOL] Profit switching pool - wafflepool.com on: January 31, 2014, 02:37:22 AM
Exactly this. Other pools have been quick and easy to test, using middlecoin as a baseline.

Easy yes, but quick no. Given variance you need to test for quite a while to get a realistic comparison, otherwise you are just comparing luck  (mostly on the smaller pool, but even on middlepool as well).
13750  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Ethereum: Welcome to the Beginning on: January 31, 2014, 02:31:22 AM
People looking at doing "IPOs" should look at how real startup financing and IPOs are structured in terms of liquidity protection for the investors and relatively little money generally going in right up front and more money going in later once some level of success has been achieved.

I'm not even talking about legalities here, just the basic economics and motivation of why startups are structured that way. In summary, real startups who are looking to create value will have no trouble with this structure (and will themselves be rewarded if successful) but get rich quick artists and other scammers looking to enrich themselves at the expense of investors will not find it attractive.

As a founder/startup, you want to align yourself with the former group not the latter. How you structure your offering says a lot about your motives (perhaps unintended).

13751  Economy / Trading Discussion / Re: Is buying Crypto with Cash illegal? (USA) on: January 31, 2014, 02:27:43 AM
Hey guys,

I've been trying to buy some crypto and someone just told me that it is illegal to buy crypto with cash, especially in the USA because you would be considered a payment processor??

Can anyone confirm this? If you have any documentation I can read over that would be great.

I'm looking to make a buck, not get locked up.

In theory, probably. Not much you can do in the USA without potentially breaking some law. Google the book "Three Felonies a Day."

In practice unless you are running a business and/or using the BTC in connection with illegal drugs, etc., you have nothing to worry about.

13752  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN][POOL] Profit switching pool - wafflepool.com on: January 31, 2014, 02:19:44 AM

Are you aware of an actual problem caused by the switching method? As far as I can tell this pool is designed to switch very efficiently. Our earnings here should be excellent.


No, which is why I asked the question. What I was seeing on the stats page "seemed" like inefficient hopping. And yes, the potential has looked good, which is why I'm here testing on day 3. The cows got less than 24 hours from me, and hashbros even less. I'm still on middlecoin as well, and while wafflepool did better yesterday by about .002/MH, middlecoin is absolutely killing it today.  I'm at .018/MH over there, not counting my unexchanged having almost doubled.  I'll get the chance to compare to wafflepool in the morning. The way things are going though, I may just keep my rigs divided for a week or two to get a truer long term outlook.

Middlecoin is like 40x bigger than this pool so you will definitely see much less variance there. Whether expected earnings are higher or lower is hard to judge especially since middlecoin is so opaque about what they are doing. I guess only time will tell. At this point it is a bit of a leap of faith (plus lower fees here).

Is the opening of ports 9333 and 9332 on the firewall only TCP or does UDP need to be open as well?

No, just TCP

Then I am not sure why the bitcoin graph on one of my miners doesn't update when the miner is outside my network, but it does update when the miner is inside the network. The hashing graph works while the miner is inside and or outside the network?

Almost certainly some other kind of network configuration problem.  Firewall still not right, bad gateway, netmask, etc.

This guy is correct, and to expand a bit further: wafflepool (in an attempt to make our servers cry less) set our max miner difficulty pretty high, so variance goes up for shares submitted, but overall profits stay the same.  Less load on our servers, slightly less accurate mining speed stats.

One idea would be to scale the hash rate calculation by shares. Instead measuring shares in the last so many minutes, measure minutes for the last N shares (with N chosen to give a reasonably accurate hash rate estimate). This will give slower hash rate estimates for small miners, but more accurate estimates.  Or likewise some similar exponential moving average which might be easier to compute.

Definitely an option.  If we have enough complaints/confusion we'll look into switching it. Would just take some database index changes (everything is optimized for time-based currently) Smiley

Well if you just keep the timestamp for their one previous share and EMA off that on each new share that requires minimal database structure.

Unfortunately, CoinedUp doesn't have a useful API (no automated trading) so to add the coin, everything would be have to be manual (tons of extra work, and increased risk to price fluctuations), so I don't see MEOW getting added until they are traded at an exchange with a better API (or coinedup adds one)

Unfortunate but entirely understandable.

Suggestion: Display a luck calculation for 24 hours, 7 days, 30 days.  We're spending a lot of our mining time now trying to get big (profitable) dogecoin blocks, which is great, but since we haven't hit any our luck is probably negative. Showing the luck will help reassure miners when rewards are low due to randomness.

Well the luck is better now! And thankfully that was right after I increased my hash rate a lot.  But it still would be nice to show it.

EDIT: Also, can we add MEOW. Seems to be the hot coin now and a good fit for this pool. (Assuming coinedup is supported as an exchange.)

Still this.

Also wondering if we're switching too fast between coins?

When I was running blades I used bfgminer as the proxy for this pool. Worked great. You might try that.
