Is wallet the only proof one has of his bitcoin?
Can it be owned or kept in any other way? Like in literal or real rather than currently available only virtual way?
So all the bitcoin one owns is actually the wallet/s he has?

hello guys how are you
i received a sms today that said 0.01 btc sent from your wallet
i check my btc address after that i see to transafer from my wallet to this address:
1bMbxGMqzeDdC9yBz9Sj3Rofb2ghcTfRt

what should i do now?

I'm not sure if this has ever been implemented yet, but can you imagine a way of paying with Bitcoin by just using your own body?

It would be more of like a microchip implanted into your left or right hand that would contain both your public and private keys to send and receive Bitcoins.

So in case you want to send or receive some BTC, you would just pass your hand over at a scanner and it would perform the desired operation. This is would make it a very convenient and easy way to transact, and carry your Bitcoins with you anytime, anywhere. However, the only thing to be considered would be the security of your private key from within your implant, to protect your funds from theft.

Nevertheless, I want to know your opinion about this, since it would be pretty cool to have such a system to help spread mass adoption of the cryptocurrency. 

Hi,

I have tried to send 10m BTC to a friend 1:30 ago and it has not been confirmed yet! When I check Blockchain.info, the transaction is not there yet and I see hundreds of transactions per minute appearing there. Considering that miners will choose highest fee transactions first, low amount transactions will starve for confirmation... I have chosen the fee recommended  by the satoshi client and it says that it is probable to be confirmed in the next 25 blocks (250 minutes!). It seems that there is bid of fees and high amount transactions are more keen to pay a higher fee. Therefore, I believe that that speech of no transaction cost with bitcoin has become a fairy tale...

Somewhere while surfing I read popular sites often makes less known sites use the money to pay first then scam and then continue on the popular sites. Could this also be happening in the Bitcoin industry. Start a roll dice or casino, open a hyip and then hyip goes scam and front site continues, no one comes to know. Or this is purely speculation, none of this happens?

So everyone says it's such a bad idea to accept paypal payments for bitcoin since charge backs are so easily done. But how is this not a major problem for every other product?

If you are selling cellphones or anything for that matter, why are you not all paranoid about accepting credit/debit card payments? But as soon as bitcoin is being sold everyone warns countless times to not accept a credit/debit card? I don't get it    

edit:
To answer all the people saying they can file a claim with paypal for item not received, you can always agree with the buyer to ship an empty envelope and tell paypal that it's a gift card so paypal can see a tracking number but you and the buyer are really exchanging bitcoin without paypal knowing. 

I am getting the hang of them more and more, and it's so hard not to bet everything away, LOL! My fav is freebitco.in though. Gosh... I have 20k sat there from the faucet, and all I want to do is use it all for betting, ha!

I am not addicted; the 20k is still there, but wow... I have an itch to scratch for sure.

I have a lot of tricks bitsler. and just last night I get a new trick? here and give it a try has been getting a lot of doge. Do you believe the trick? and until when these tricks can be used https://www.youtube.com/watch?v=U1bMVOKFTPM

When that time comes that the price of bitcoins will be $100,000 will you still gamble in casinos and sports books?

If the price of bitcoin is $100,000

0.001BTC/1mBTC/100,000Satoshi = $100
0.0001BTC/0.1mBTC/10,000Satoshi = $10
0.00001BTC/0.01mBTC/1,000Satoshi = $1

1 Satoshi = $0.001

If the government came out today and declared that Bitcoin cannot be accepted as legal tender for purchases, I believe Bitcoin would find a way. It would find a way only because of the anonymity that today's cash affords people. Cash is the lovely bridge that people use in turning their Bitcoins into value.

Tomorrow though, when there is no longer cash and the only form of payment is electronic, and where all electronic payments are handled by auditable pools of companies, what will happen?

If you want to look how that might look in the future, look at a company that already functions are entirely electronic payments.
Take a look at Amazon: If Amazon was ordered not to accept Bitcoin, and cash no longer existed in the world, how would one be able to use Bitcoin to purchase things on Amazon?

In order for Bitcoin to work in a world that is hostile against it, it needs the anonymity of cash. What happens when that goes away?
Would love to hear anyone's thoughts on this dilemma I've been having.

So much so that 15% of banks world wide expect to widely implement blockchain, which is a ledger of transactions updated in real time by various institutions, by next year, according to the report which surveyed 200 global banks.

These banks, mostly medium to large-sized institutions, are focusing their blockchain technology on three areas: consumer lending, retail payments, and reference data, which refers to the real-time information sharing of transactions across business divisions and institutions.

In four years, IBM says that 66% percent of banks expect to have blockchain in commercial production and at scale.

Well, I rent hash power on nicehash and I spend 0.01 btc. after spending all of it, I only got 0.0004 in return. is renting hash power profitable? then why many people still renting hash power on them. am I doing something wrong?

“One of the keys to a trader’s success was not the results of a trade but rather how a trader reacted to the results of a trade.” – Dan Gamza

Why me? Why did this happen to me? Those are some of the questions that disturb losing traders. After a series of losses, some of them develop hatred for trading. Suffering that results from negative trades, drawdowns and margin calls can make people easily disappointed in trading.

Nonetheless, no matter how bad your trading is, it could’ve been worse. No matter how bad things are, there are still some reasons to be thankful, if you can think deep.

There are events that move the markets and which professionals focus on. These events often are filled with uncertainties, bringing profits and losses to people. Just some months ago, Greece was a hot topic, and speculators were mulling opening positions on the seemingly overextended markets, but some had serious misgivings. At times, the stakes may be higher than the rewards.

There Is Really Nothing Like Losses
There is really nothing like losses, for what brings losses to some people is what brings profits to others. The market moves up or down – not losing up or down. When you buy EURUSD and it goes up, you win (but a seller will lose). When you sell AUDJPY and it goes up, you lose (but a buyer will win). When you enter a direction in the market and it moves seriously in your favor, all those who go in that direction will make money, provided there are no wide differences in their entry prices.

What you call losses is what brings profits to some people. What you call profits is what brings losses to some people.

People Don’t Learn Their Lessons
Despite well-meaning efforts to solve the problem of loss, there are millions of traders around the world who’re still losing because of dangerous trading habits. People don’t learn their lessons.

During a funeral process, many attendees will be remorseful, thinking about the brevity of life and futility of wickedness, anxiety, love of money and so on. But once the funeral is done, you’ll see many of those attendees living their lives as if they’d not die again.

Too many traders lost in the past because they didn’t use stop loss on live and simulated accounts. When they come back to trading, you’ll see them using the same trading approaches that led to their downfall the last time, namely, high lot sizes and no stop loss. People don’t learn their lessons.

Traders who test new trading ideas on demos don’t use stops; and I wonder how that idea can survive on live accounts in the long haul, because they may apply it to a demo account once they’ve been lucky enough to gather some gains.

A Way Out?
After many years of grappling with the markets, traders who complained in the past may later show their gratitude; and for the fact that the markets cannot be blamed for what happen to them (though we may feel disappointed sometimes). There are days when they become sad, and they complain when they think of their seeming helplessness. Nonetheless, they’d have come to understand that the markets don’t set out to punish individuals.

Interacting with good traders as well as reading about super successful ones would’ve made them stronger psychologically and kept their spirits up.

Reflecting on a possibility of a risk-free trading approach reassures those who’re currently losing. Good trading coaches care about them, knowing full well that the end of their struggles is in sight. Focusing on such hope can give a trader the fortitude to endure certain negativity now.

Conclusion: Are you disappointed in trading? Well those who currently make loads of money from trading were once disappointed at some time in their careers. Those whose marriage is now successful were at one time, frustrated by their spouse. But these people, for example, profitable traders (as well as happily married persons), looked for solutions to their problems and apply those solutions faithfully. That doesn’t mean they’re luckier or better than others: that means they’re able to overcome the causes of frustrations and disappointment in their careers.

Hi, i believe the bitcoin will be the currency of the future
and it's a threat to the federal reserve
but they are not going to just watch their system collapse of course
how do you think the federal reserve will react ?

Just sit back and relax fellas.

Bitcoin just snapped into awesome mode.

Nothing can stop it now.

Watch all other currencies sink and die a miserable death while Bitcoin soars to all time highs in the near future.

Bitcoin = 1
The rest = 0

Europe is the world's largest economic zone with a little larger GNP than the USA.  Yet we have all heard of the severe economic (and cultural because of migrants) problems.

I am an American but very much a "Friend of Europe".  In the parts that our family has visited, we feel pretty comfortable, as European values are pretty similar to American ones.  The food is good, the infrastructure probably better than the USA's.

Here in this thread, I invite discussion and comments on where Europe is heading.

Martin Armstrong (an economic forecaster who has a fan base and a huge supercomputer grinding out economic analysis) just wrote the below short piece on the prospects for Europe breaking up:

https://www.armstrongeconomics.com/international-news/europes-current-economy/europe-starting-to-break-apart/

* * *

I particularly invite Europeans to comment!  We (I) need perspectives from bitcointalk members as to what you think is happening there!  Here is a list of various subjects all pertaining to Europe now, but I encourage comments on anything that forum members have.

--  Migrants from Muslim countries (appears to us Americans as a huge problem)
--  Continuing problems in the banking system (both "Club Med", but also even mighty Deutsche Bank)
--  Do Europeans living close to Russia view that country as a threat?
--  How likely would you see a break-up of the Eurozone or the Euro currency?

Last year, if I remember correctly, bitcoin spiked around Christmas time. It's that time of year again, and are you guys ready for some volatile action? Well I am!

I'm expecting the price to jump to almost $900. How about you?

What will be the medium of exchange for the world economy after the collapse of the dollar?

I have noticed that many Bitcoin users are quite liberal, and wonder the reason behind that. Conservatives believe in small government, limited tax, less regulations and free markets. Liberal policies would without a doubt hinder Bitcoin growth with intense government regulations and scrutiny.

Two years ago he threw a bitch fit and said if we don't increase blocksize, the network will die.  Now, Circle is taking their $138 million and leaving along with many, many others.  The congestion has jammed up the network and it is no longer useful.  While we still have our pure values of decentralization, we also have a dysfunctional system that no longer serves many of the original intents. 

We should go to 8MB today.  Keep building LN so we don't have to one day go to 16MB.  That way, all involved in making blockchain projects will stay with Bitcoin instead of running away to other FinTech like Jeremy Allaire. 

We CAN have it both ways!  8MB is the new 'small block'.
