Obviously there is no real way of knowing but I am sure that a large majority of the dump is made up of Chinese investors. Currently one exchange is confirmed to be closing down and others may follow. The investors have really only one choice and that is to dump their coins whilst they still can. Of course some will also be from people who are panicking.

In my opinion, real. I think probably the exchanges have been told either 'shut down or we will shut you down' or alternatively something along the lines of 'comply with x y z conditions or we will require you to close'. It will be a big hit to the market, however I wouldn't be surprised if China will somehow try to nationalise an exchange or create a national exchange so that they can more easily monitor what is going on and also profit from it. These are just my thoughts however and they aren't based on much.

Really you need to forget about the price you first paid for btc because that is fairly irrelevant. Right now you have x bitcoin worth x amount each. You've got to decide firstly if you want to sell them or hold on to them. Further to that you've then got to decide, given the current price, if you would like to invest in more bitcoin or not. Most people are of the impression that the price will rise again towards the 5k level which would be a 505 increase on any investment right now, so if you are of that belief then it is a good time to buy.

I think you need to look again at your market cap for ripple  it would dwarf the other 3 coins if the price and supply were correct!

For a lot of people there will be mental barriers at which they will sell, generally whole numbers so 3k, 2.5k, 2k. For most people though they will now be looking to invest in more bitcoin at a good time instead of selling their coins. The likelihood of btc not recovering to 5k soon is somewhat reasonable but the likelihood of it crashing far below the current (approx 3.3k) value is much less likely in my opinion.

It is in interesting point of view regarding reaching euphoria, I think we are actually a long way from that stage. There have been a few major hits to the market in the last couple of weeks but the market seems to have far a large part just soaked it up. A large part depends on where you see btc ending up, if it is to be a success and a mainstay then I think the idea of the price reaching a stagnation point is quite likely, however if btc were to fail for some reason then obviously the only stagnation point is zero.

Personally I think 4k is a good entry point, bitcoin was nearly at 5k only a little over a week ago and will likely hit that level again soon. However no one can predict the future with certainty so be cautious with what you invest.

Personally I use bittrex and occasionally hitbtc or poloniex. The fees are lower on hitbtc than the others but I don't like the look and feel of the site as much and more importantly I don't make as much due to the smaller volume.

The overall value of my portfolio has fallen by about 20% from a little over 11000 to 9000 now. But I sold nothing so if the price recovers in the future then I will not have lost anything and I never even had that dollar amount so from my initial position I have gained money, it is always important to remember that in my opinion.

Personally I look for coins which have good spreads, especially those that are backed up by big offers so the risk of losing greatly is largely reduced, I don't aim to hold the coins for more than about 4/5 hours and aim to make 2-5%.

Ark has great potential and is growing nicely but I think for it to surpass Ethereum is quite a long stretch. Ethereum is established as one of the top coins and is expected to continue to grow. For ark to reach the current level of ethereum is still quite a stretch but at that point in time Ethereum will likely be at a much higher price.

I can't see bitcoin ever becoming a national currency. There are many issues for any country trying to adopt bitcoin as 'their' currency. Governments normally have control over the supply of their own currency so that they can use this as a tool to manipulate the economy where and when necessary. This would not be possible with bitcoin. Furthermore bitcoin is very volatile which would not suit the needs of a country looking for a suitable currency.

The biggest piece of advice I can give is to specialise in trading 1-5 coins first using one strategy, study these coins and their trends, once you have 'mastered' trading these coins with this strategy then begin to look in to more coins and strategies and expand outwards from there.

My favourite is definitely bittrex but this is perhaps just as I do most of my trading there. Overall I find their site to be the most pleasing to use unless ofcourse we are talking about on a mobile device (as previous poster said), on mobile the graphs are very hard to manipulate. I guess the answer though is just don't use mobile for viewing graphs.

In terms of overall profitability I would suggest the crypto market as it is a lot more untapped, with less experienced traders and less sophisticated trading bots. However the crypto market is also a lot more volatile and a lot less predictable in my mind, therefore the risk is much greater.

There would be a few benefits with using one currency such as reduced transaction costs and greater price transparency but the main issue lies in the fact that different regions have different economies and any shocks to these economies need to be accounted for in terms of changes to supply/demand/price. In the case of their being only one currency it would take far longer for these changes to occur which could lead to greater unemployment. I think that is the jist of it, we did a short paper on it in class a few years ago.

Thank you for the prompt response, I think they tried around an hour ago so I have told them to try again 

Hello, a friend of mine tried to sign up for the 75 free tokens but didn't receive the email to confirm their address, is there anyway they can request for it to be sent again, it's possible they could have typed their email incorrectly?

The pump is coming, be patient! As for 3 weeks time I think that is probably a little too early. Give it till the end of the year and I think Ripple will have flown up!

OP what's your source?
