It is crucial that they don't do it. Because if they do, they won't be able to spend their coins anywhere, or sell them, since nobody else is running their code. Their coins will be worthless and they'll have wasted their money mining them. It makes no difference whether they have 51% or not. Fortunately, miners are smarter than OP and won't do this.

It is already easy to spend BTC. It is becoming easier to buy and sell BTC.

To close the cycle and have a real Bitcoin economy we really need some way for millions of people to be able to earn BTC.

Thankfully there is a simple way to achieve that:

https://www.fiverr.com/   millions of gigs, already takes Bitcoin for funding (via Coinbase)

https://www.uber.com    Over 1 million drivers worldwide      (works with Braintree/Paypal)

https://www.airbnb.com/  34.000 cities, over 1 million listings (works with Braintree/Paypal)

https://www.freelancer.com/  15 million users. 8 million projects. (works with Paypal)



If we can get just these 4 to do Bitcoin payouts for contractors, it will give access to millions worldwide to earning BTC. Anyone with a house, a car or able to work will be able to #EarnBitcoin.

The payment processors are already in contact with these companies and have been offering the option to receive Bitcoin payments... how hard can it be to offer the option of Bitcoin withdrawals/payouts?

i know bitcoin itself is already an investment but i have 3 bitcoin sitting around and I'm looking for a quick 5% flip any idea??

Recently we were caught up by the whole debates and now another problem came up in which damages BTCitcoin image (again). Recently for the first time, a known ransomware for Macintosh has hit users and as result, demands 1 BTCitcoin to not ruin whatever they get their hands on. Things like this, make me feel like, hope there was a way to prevent these types of crimes but it's completely out of our ways apparently, so to all users of Macintosh out there, be advised.

I see there are so many people buy and sell with paypal, but do you never met any scam buyer/seller who take any cheaps to report you and led to your paypal account is closed?? just yesterday, my paypal account was killed, so my store reduce an accept payment.

and I guess everyone have known that BTC-related transaction is dangerous on paypal, but how do you treat it? did any people buy/sell Bitcoin with Paypal in the long term, but had never been punished by Paypal yet?

thanks firstly for your valuable experice   

I want buy BTC. If i send from my PayPal account to someone else PayPal account money. Can this person scam me? Is there option that i can't make chargeback?

hey all is here any trading bot app for android where can i set the price of bitcoin and can trade in market with zero risk while sleeping too.

I need to buy a small amount (like $20 a month) worth of bitcoins to pay a service.
I do not want to provide an ID or associate with my credit card.

I prefer to do it online as well and not in person.

Can anyone please advise me on how to do this?

TIA!

Okay so I don't really have any idea which coin is which and which of those are good to trade and which are not.
Since I am currently enrolled in yobit campaign, I figured maybe I can do something profitable with the coins that I get from the campaign so I thought maybe I can start trading.
Do you guys recommend yobit in trading altcoins?
Also what coins do you guys suggest I trade? I want profits and not loses so any tips you guys can give me are really appreciated.

I have some coins idling around in my wallet but I cannot bear to put it in hyip or risk it. But it is a waste to let it idle around. Yes. I have coins in some "lower risk" hyips to generate some interest which I'm prepared to write off. I also have some coins converted to hashing power in hashnest and BW.com but it has to be monitored else you will suffer a loss instead. 


Unlike fiat currencies, I cannot park these coins into banks backed by governmental institutions. I put my fiat currencies in banks or blue chips but I cannot do it with cryptos.

So, what do you do with your idle coins? Let it sit around?

so seen some companys that offers bitcoins debit card what is the advantage of having them?

anyone using them what is the transactions fees am courius

Should i buy my first whole bitcoin ?

I just want opinions, would you buy a whole bitcoin ?

Since I woke up this morning , I've seen several topics and people complaining about their transactions not getting confirmed ? Is it a coincidence or there is something going on ? Spam attack or something similar ?

Hey everyone,

Just wondering, what percentage of your total funds do you usually keep at a single exchange?

I mean, what is your risk mitigation strategy, considering the many exchanges that went kaput?

Hi. I’m doing research on what people who are interested in Bitcoin and other e-currencies think about money, currency, and governance. If you have a few minutes, please take my 5-question survey.
Your anonymous answers will help me do the research for my B.A. thesis (with a small possibility of disseminating the results through some kind of publication in the future). Click https://www.surveymonkey.com/r/T7HLXSD to get to the survey. Thanks!

Read a little about history of NXT, while jumping ship to ETH as a store of value. Compare the following two graphs...

a. http://coinmarketcap.com/currencies/ethereum/#charts

b. http://coinmarketcap.com/currencies/nxt/#charts

Compare the following facts...

i. NXT was backed by a centralized organization, just like ETH.

ii. NXT was PoS, just like ETH will ultimately be.

iii. NXT offered asset exchange, while ETH offers smart contract. Both of these functionality, which they claim to make them unique, are actually possible on bitcoin blockchain, which is far more secure.

iv. With price rise, NXT backers sold their holding to increase liquidity in the market. With price rise, ETH backers are increasing ETH supply in the market to increase liquidity in the market.

p.s. Alt coin trading is a gambling. If u wanna test your luck on some coin under pump, its fine. But, make sure to come back to BTC, when u have made enough, otherwise u'll lose all and have to be a mute spectator while the next alt wave hits. GooD Luck

So, what do people around you (relatives, co-workers, co-ed, friends...) think about Bitcoin ? Please, indicate your country, so this way I'll be able to make a synthesis about what people think about Bitcoin.

For me : I come from France. My relatives think that it's criminals' tool and that since they can't touch money they don't trust it (note that those same persons are pro-banks, where you can't touch money). My friends think that it is useless and that it has no future. Both of them agree that scare them the most is the Bictoin's price volatibility.

So not so positive . I hope that you aren't in the same situation.
