Are you into trading? What coins do you like to trade the most and what's your trading startegy?

Facebook, Reddit, and Twitter are particularly popular platforms for discussing about Bitcoin and sharing information.
There are a lot of great people to follow on twitter. Check out cryptomanran, venturecoinist, and cryptobully
Also there are some solid sites like Coindigo.
I like Coindigo so much because they put together all of the investing research you could possibly need for tons of coins. I can just read one article on there rather than having to do hours worth of research.

Yes, it's a matter of legality and the sites selling coins needing to keep track of customers. Besides, most of the governments of the world really want to know exactly how much money you have and where it is at all times so that they can seize it form you at a moment's notice on their whim.

May be it s a fake news..I would to know if is Circle basically Goldman Sachs?

The wisest way to start is to train yourself through what is called a virtual wallet.
Most specialized sites offer, I invite you to do a search on the net with the terms "virtual wallet".
This one will allow you to simulate stock market operations, to see the evolution of your investments without putting in play of real money.
When you feel more secure, you can open a securities account / PEA on which you can invest real money.

The Bakkt project brings together several major groups who will join forces to offer a mixed solution adapted to the integration of cryptocurrency (and Bitcoin in particular) in the very diverse uses of everyday life. It has just been announced today.

The various groups concerned at the moment would be notably the ICE / NYSE, BCG (Bolton Consulting Group), Starbucks as well as Microsoft.

This mixed solution will initially include future Bitcoin sales with physical possession and storage of the relevant bitcoins, managed by the NYSE on federally regulated exchanges. Bitcoin is the first considered because, according to the ICE, it is the most liquid cryptoactif of the current cryptomonetary ecosystem.

Crypto-currencies in general are not dead and they still have a future. But their adoption will not be as fast and important as most fervent supporters of cryptocurrencies thought.

It will stay, last and play a role in the ecosystem.

Simply put, a lightning network is needed to speed up the transactions of a homeowner, which is very important at the moment.

This is a scalable solution to the bitcoin scalability issue that was released in January 2018. The network will use an off-line protocol that is under development. The P2P system will include mini-payments of the digital legacy currency through a network of bidirectional two-way payment channels, without authorizing trust or trust to third parties.

 I would know if it is possible to send BTC without a transaction fee regardless of theoretically or practicall..

It is a simple & very common thing in trading market, buy at low price. In a up trending markets, the price will move upwards with several correction to the downside. In up trending markets you want to be buying only. Dips is a correction where price falls in the short term. As a bull, you might "buy that dip".

There are many languages of programming on which you can focus your efforts and the choice of digital money you want to use can serve as a basis for fit and usefulness. It is also essential that you reflect on the best programming dialects of 2015/2016, distributed here by IEEE and TIOBE.

To create a strong cryptographic programming environment, I would recommend focusing on the first learning of C ++ using a few learner books (if you are on a tight spending plan, you can really buy a considerable number of these books from an adjacent store). Goodwill or library used for 1 / twentieth of the cost), and then start trying different things with Node.JS, Python, Perl and other applicable dialects as they are normally perfect / recognized / enhanced under initial cryptographic conditions.

For explicit programming with crypto innovation, you can focus on C / C ++ with OpenCL / Cuda for GPU programming. As there is a massive capital and subsidy measure now asserted and devoted to crypto-innovation framework and engineering (and all is well, block establishment is vital), you can get a return on investment high by focusing on these regions and administrations and devices (C or C ++).

We risk losing a lot of money if we do not know what to do!

In this case it could be very profitable, especially when the traffic is huge. Quickly trading the ups and downs requires a good reading of the curves and the identification of the technical indicators that are formed influencing the majority of traders to proceed with the purchase or sale.

Otherwise the simplest would be to seize opportunities punctually. Buy when the market is very negative like at the moment and sell after when cryptos reach new records!

It is always difficult to answer such questions because we do not have a crystal ball available. It must be understood, however, that the cryptocurrency market is a market manipulated  by big investors better known under the name of Whales.

The vertiginous fall of the market since early November 2018 is clearly to look for a manipulation of the market by these famous Whales. So the big question now is when will they restart the market once they strengthen their positions at lower prices. Some argue that the Bitcoin will start again in early January 2019 before increasing more and more in the approach of launching futures by the parent company NYSE, the New York Stock Exchange. The new dedicated platform will be called Bakkt.

Nevertheless, nothing is sure. It is therefore impossible to tell you if crypto currency is a good investment for 2019.

The main obstacle now is the relative stability of the political and economic system, most people being satisfied with the means of payment at their disposal (fast and simple).

But the situation will change when the population loses confidence in the financial system and the currency, which is sure to happen.

What will happen when Italian banks run out of cash? what will become of the euro if Italy is defaulting on its debt? Salvini having already warned that he would not accept a troika as with Greece.

In case of no-deal, will the Brexit drive the UK into a recession? what impact would this have on the rest of the already fragile euro area?

And, finally, perhaps most importantly, what does the reversal of the yield curve mean?

I hope the decision of the court goes into the favour of cryptocurrencies as a lot of rumours has always been heard now and then which has created a lot of fud and fomo,we need some good news to make btc back on the bull track....

Bitcoin has value as money, because it makes for very good money. It has grown in value because more people have recognised its usefulness as well as its fundamental integrity. As the consensus of Bitcoin as money grows then so does it's value as a money system. More users makes it more useful. If we all used Bitcoin for every day uses then its value as a money system would grow some more.

G-20 Classifies Bitcoin as an Asset..These countries appear to be moving toward a consensus that cryptocurrencies may not be currencies at all but rather that it might make more sense to consider them as assets.
