Sale something through FB costs a lot of money and you can not get them back. If people are clicking on the link nowadays, this do not mean that they are going to buy something. There are clickers from India, Indonesia etc, which do not spend even one satoshi to buy something. 

They can not spend them, even if the try to buy/sell in BTC exchange market. On average all users are buy/sell with ~ 5 - 20 BTC and not more.   

Online wallet for ETH do not exist yet, so the only choice is to use desktop wallet 

It sounds like scam site, there are a lot of many BTC scam sites everywhere. It is very hard to say is it BTC site, which offer profit or scam. 

Just think in which country is largest Forex companies - in USA, so all deals are going in USD. 

The first advantage is if you win a lot.  And the second is that sometimes there are chats in Dice sites, for example, and you can ask for the best gambling strategy, best BTC sites etc.

Yes, just think, what can be the future decision of the debt - it is very large sum of money. I think no one even know what to do with this debt 

Ransomware in the hospital software - probably one of doctors download something. They ask him to leave after this from the hospital, I think. 

Make some good steak with even two cups of strong coffee. BTC hit 420 probably this year in June or July. 

Try Dash mining, because after mining you can convert it to BTC and get profit. 

In fact there are many BTC users worldwide, but it is hard to understand how large is BTC market. If you look in latest China BTC mining farms, you have strong feel that BTC will be forever. 

If site will pay well, then there will be users - so good BTC investment in the site can help. For example you have 10 clicks, and then site pay you - 0.01 BTC. Otherwise I can not see many BTC users Web around. 

I check after some time - if there are many users Web around for this crypto. This is Nr.1 for me and most important. Then I check, if transfers are going ok 

You can see real market price - buyer price and seller price. Simple as that. Some more Chinese BTC mining farms and BTC worldwide price may be go down - the buyer price will be lower. 

Linux version is a must for this nice miner. Not all people using Windows. 

Bitcoins will be in the market and I think banks will implement them in their payment systems too. 

Very good software for mobile, when you can always check BTC market. Your mobile and TabTrader is always with you. 

Bitcoin is much better, because first of all you can transfer it completely by yourself. With Paypal you use their own system 

Yes, oil prices are very low from some time ago, for car drivers this is very good news .  I think low oil price can make some headache to large oil sale companies. 

I like 8 hours plan.
