Yes you nailed it. There is no comparison between bitcoin and PayPal as bitcoin has so many features and jargon free which we cannot find in PayPal and cannot expect as well, In other words PayPal is a failure method and Bitcoin is the future as day by day more and more merchants have started accepting BTC and more countries are going cashless so there is a lot in store for BTC which PayPal can never achieve.

@metalmag = For Mining, if you need to use AC, you're not doing it right.  Especially if your region upper temperature is that cool.  Again I'm in the 40C in the summer and others are even higher in Arizona and we can do it fine.  Even if you have free Electricity the cost of buying, installing, maintenance, etc is very high.  Let's do some quick math.

Assuming Free electricity.

10 Rigs = 4 TON AC @ $4-7K each depending brand and SEER levels installed.
100 Rigs = 4 x 4 Ton AC  $40-70K.

1 x 4 Ton uses at peak up to 60AMP.  So you're wasting 600AMP just for AC alone!  Now you have to factor in that you will need around 600-800AMP more for your 100 Rigs so the total is up to 1400AMP.   Even Commercial space the transformer may not be powerful enough to handle 1400AMP as you're sharing with other tenants.  You can request for more power if it's available but they will charge you for it.  Now this isn't even taking the consideration of the 80% rule which means you really need at least 1700AMP.  This is taking you into Industrial spaces which requires very large warehouses.   So you're talking about something you can achieve for less than $40K which includes 600AMP of power to drive your rigs into something well north over over $200K and require special zoning to accommodate.  If you design your environment right, you SHOULD NOT need AC.  Mining is a Mathematical game.  Even at 3cents / kw, you won't even be able to compete against someone with 10 cents KW even you have to use AC.  I would invest that money into more RIGs and a better layout / exhaust strategy. If you have that kind of budget, it shouldn't be hard.  To win in this game you must keep your cost low and invest the rest into HASH.

@yslylung - Yes Finksy just got his 150 Picos in.  Your price is very competitive for a custom solution.  Finksy's cost is actually still lower so there's a small margin for reseller on top but his goal is to keep the cost as low as possible for the community.  He's sending me 20 units to test for my different Prototypes designs.  I have 10 of the HP 1200W including the V6 breakout boards plus more 4KW to play.  There's never a 1 size fit all solutions and always pros and cons with every options.  The HP solution is best if you can get them in bulk for $20 or less each as there's breakout boards $25-30, Pico $30 and cabling cost $18-25.  That brings you to about $105 for the normal consumer.  People will always argue that you can buy a ATX for almost the same price with better future resales, yadda yadda.  Maybe you can during hot sales but the cabling and configuration will not be as sexy.  The issue with this solution is that many people in America use 120V which this PSU can  only deliver 900W vs the world on 240 which this PSU can deliver 1200W. I don't have this issue so I'm not concern.    Also the HP 1200W have only 1 TINY fan, I'm not sure how well it can handle the heat but man does that fan make a LOUD pitch noise!!  This thing is definitely not something I want to run inside my house.

For large miners the 4KW is important as they don't want to rearrange rigs after it's installed in the RACK.  They also want be future proof and plug things in and never have to really think about power usage later one.  Heck most people didn't even know that ZEC and ETH first version and current version consumes WAY MORE power.  So if they're sizing based on original estimates, they're screwed.  However as you said, if you have a PSU go down, you're not just affecting 1 rig but multiple.  That's the downside, the upside is that each breakout board and PSU is so cheap, there's no reason why you shouldn't have at least 1 spare bundle if you're a large miner.  Swapping is super fast and simple.  Efficiency for PSU is also better when you're using less than 70% of load and that will be harder to do on the HP.   I like bother solutions and at the end of the day, paired with PCI Risers and Picos, I'm really liking the Server PSU setup so so much better.  No more clutters.

I have design prototypes that will take advantages of both the PROs on each solution.  At the end of the day, if you're a large farmer, you will have a variety.  There's no solution that can meet every need.   But I do think that once people see more of the cool server PSU and PICO designs now that we PCI Powered risers, they will LOVE TO GET their hands on these PICOs.

The air is pulsed from the ground through grilled plates that replace the normal floor plates and pulled by negative pressure, made from the racks intakes and the hot aisle separation/ceiling air-pull, this is the most efficient design as air cooling goes, and the sad part is that you have plenty of datacenters that aren't respecting it fully, even though it has been invented for nearly 25+ years now. You also have some system variant, but the principles are the same.

Cryptocurrencies are vastly superior to typical fiat currencies, but they are nowhere near as convenient at the moment. It will take a long time until a bitcoin world appears. For example, if you wanted to pay for a beverage like a Coke with Bitcoin, as of now it would be take around 30 minutes for the transaction to be confirmed, not to mention having to input the restaurant's address. It is just much quicker to hand over a note and get your Coke instantly.

Thanks for the compliments. I know what they do to take up a deal as I was once in that race when I started  .

See what I believe that it is first upto campaign owners to decide who will be managing . Of course , they look for a pack of things in a campaign manager and that is the point where most of the campaign managers differ.

And BTW a campaign managers need a portfolio . is it right? Yeah I think it gives an impact but I believe "vouchers" or "supporters" are a portfolio in itself and that is a big factor (that does not mean you don't have to keep portfolio). Take for yahoo case, he is known in this community for long as a good signature campaign manager and he now has many active campaigns. I don't think he personally send portfolio to the client . He don't have to because his vouchers and supporters places impression how much he is good in this before the client.

I guess somehow you did that for me too lol ,thanks

And,yeah I never get offended . Even though I smile at tries . But yeah I think that's the reality what you said there so I didn't take it as personal.

There is a good future lies and there are many new campaign managers that can come out good in this. I personally have seen one or two. Ofcourse I started by a chance and now new managers also should get some .

GL to all

Also on trading there is other method analysis fundamental and not analysis technical only, that is first different between trading and gambling, there are method for make prediction of price and the method had been used by all of professional traders in the world, there are not method for win on gambling game, the other different on trading we can do stop lost if the price against our prediction and I don't know there is stop lost in gambling.

Perhaps each mining pool should create their own "accelerator" and accept payment for "acceleration".  Those that pay the highest "acceleration fee" will get to be in the next block.  The lower "acceleration fees" will need to wait for later blocks.

Oh wait, isn't this how bitcoin already works?  We pay a transaction fee to get our transactions confirmed.  Those that pay the highest fee get confirmed first. Even better, with the current system we can KNOW that the miner that confirms our transaction will get the fee.  If we use third party "accelerators" we might have to pay a separate fee to multiple miners and only one of them will actually confirm the transaction. The rest will get free money!

Perhaps a better solution would be for most of the major wallets to default to RBF.  Then the wallet can have an "accelerate" button that increases the fee paid.

Perhaps the major wallets should also have an "accelerate received transaction" button that creates a CPFP transaction with an additional fee?
