??? show me proof of one single country that really have made Bitcoin illegal.... None you will find. Only thing you will find are: "regulations" and "warnings". Especially in countries already having heavy regulations for Fiat-currencies (try to export USD from India or China).
(a) did you actually see the bid offer on these stupid binaries? it is beyond eggregious! i know that volatility of the bitcoin is high, but probability of making money is very low with this style of execution (b) i have zero views on bitcoin except that in these early stages it's very hard to predict the potential of the product. for choice, i'd be a buyer not a seller
That's just a compliance to China's regulations. It's fully legal to own and trade Bitcoin in China, if you comply to the regulations. It's the same at eBay in the USA: also there it's not allowed (by USA regulations) to trade Bitcoins with out a license.
I bet that percentage wise, there is a larger amount of criminals in Bitcoin than in USD. The incentive is clearly there, it makes it super easy for cross-country transfers, money laundering, black markets etc unlike any regulated fiat. In fact there was a whole online black market using nothing but bitcoin that got shut down by the fed. Don't see that with the USD... Also bitcoin exchanges face higher and higher barriers to entry due to their constant collapses. People become skeptic and will only use trusted exchanges. My bet is this will result in eventual monopolization, and bam, it's essentially centralized. Looking at the http://bitcoincharts.com/charts/volumepie/ it's already distributed accross 4 exchanges only. It makes little sense to argue decentralization when it's dependant on centralized exchanges, software etc. Also wasn't BitCoin mining also attempted, and almost successfully, monopolized by some supercomputer once? It seems as difficulty rises, again barriers to entry will be higher.
An atm binary (pick 'em) mkt is 50/100 fairval (excluding FX). The vola doesn't matter, just the forward. There is no forward mkt in BTC so this is an outright fleecing. They're pricing a coin-flip at 70/100.
