I read some criticism around Bitcoin, because is too volatile, but this is the reason for the success of this crypto ( and others), imo

Also, why do you need a stable coin ? If you can't pay with Bitcoin for you coffe, who cares ? I mean, it is just like gold, you don't walk around paying with gold, but you know it has value.

I just can't see a clear disadvantage on being too volatile, something that could make ppl loose interest on Bitcoin. I would like to hear opinions on that.

Hi this is my doubt about costs related to bitcoin mining.As we all know that the difficulty as well as the cost for bitcoin mining is increasing continuously,suppose now the price is around 6,400 dollars and if this goes down a little to 5,000 dollars and if it continues for a period of six months,then would it be profitable for people or companies who mine bitcoins and if they were in a loss,would they be able to continue mining with a hope that bitcoin price would increase and they could recover their losses.And would it affect bitcoin mining in future?

Your views are most welcome.

Is the crypto scene developing how you expected it? Do you find it progressing faster than you expected or slower? Does the progress please you or bum you out?

Obviously much of it is amazing, but at the same time it appears the same old mistakes are being made and some new ones too. Humanity is more inclined to bend something to its collective stupidity rather than head down a new road inspired by the good stuff.

Example? I've been sitting around in NEM since it was sub peanuts. There'd be one tweet a month about it and you'd have to sift through ten pages of google to find a relevant mention of it. Now it appears to be the basis of Venezuela's Petro, a coin 'backed' by the Bolivar, not oil or owt.

On one level this is mind blowing considering how nowhere it was. At the same time it's pretty fucking skeevy.

Maybe Bitcoin instead of going full mainstream currency needs to enter the masses through loyalty bonus point type programs. Loyalty points were really the original virtual currency....it's a lot less intimidating to the average user to collect 'points' or tokens and redeem them alongside normal fiat pathways.


Say Starbucks gave out digital crypto points with a purchase made through your cellphone or credit card. Starbucks can firstly have tailor made loyalty program that normally is wasteful and inefficient and customers have then used cryto in a way that means they almost don't need to know its Bitcoin.

There are alt coin projects like Coval moving into this area but maybe Bitcoin needs to enter the masses counciousness through the backdoor of loyalty programs? The loyalty industry is btw worth 70 billion annually so it's not a small thing.

Blockchain is called a technology that will change us just as the Internet has changed it. blockchain ideologists claim that it is about to lead humanity to a ultra-modern world where there is no theft and deception. how will this happen? Will the blockchain become the Savior of our world economy or its killer? If the blockchain is tightly integrated into our lives, the unemployment rate will increase, and on a huge scale. And this can lead to a large percentage of poverty among the population. Will the world economy sustain such a large number of unemployed, or will society be further divided into social classes.

THis is more of a philosophy topic than anything. I think about mining and how all those rigs are out there sucking down juice, making heat, just so one can get a few BTC that may or may not be worth something 10 or 20 years from now. (while I think it will, factually speaking...anything can happen it is a real possibility that btc crashes)I'm not an environmentalist by any means, I am into doing things in the most efficient and responsible way however.

This makes me think...is there a better way? Can a new coin or btc alteration be introduced that simply makes everyday tasks into mining and then use any resultant heat for something else. For instance, what if every car was a miner like say everytime you hit the brakes or mabey just attached to your engine output shaft or something of that type. Doesn't need to be much, point is not to make money. Or walking..strap a pedometer type device on and your mining while walking. What if your miners were heating homes and water (seen a few projects of this type out there already). Doesn't need much, low hashrate per everydaytask x trillions of everydaytasks being done=high hash rate.  It's the ultimate one world order without a central controlling body.
The high level advantages would be everyone could be a miner just by doing everyday things and that would ensure diversity in the mining pool for centuries. Disadvantages would obviously be why would you do this if there no real reward. Under current rules every day tasks may result if oyur lucky in 1 satoshi/year if that. I dunno....just thinking out loud really.....not sure if its viable or feasible. But interesting pondering sometimes.........

What restrictions does mining hardware place on the Bitcoin block header?

Can you give mining hardware any 80 byte header and it will search it (updating the 4 nonce bytes and maybe the timestamp)?

Does the version field have to be positive?

Does the difficulty target have to be a reasonable value?

Does the previous hash have to have at least 32 zeros?

Does the merkle root have to encode at least a coinbase for the extraNonce?

Hello and congratalations for this massive community.


Im new to bitcoins, i have used around 5 time a wile ago.

Im interesting in start learn, and get into bitcoin mining, i would like anyone here interesting in spend some time with me on skype and have a conversation where i will abord what i pretend to do.
