There is a sense of nervous anticipation heading into the Constantinople upgrade, mid January. We've seen how the hard fork hit the BCH, but in ETH case it can be the other way round.

I think more people will move from just holding and buying coins to actively trading, trying to get the most from the volatility.

Some of the altcoins are backed by existing working projects. So the question is too hypothetical, as for me. If all cryptos die, they all die. BTC won't be an exception. Such an unlikely scenario anyway. They can fall in prices, that's true.

It's not exactly the best time to invest in new coins, if you look at the market conditions. Just an opinion.

The good thing is the working project behind it. Too early to make any predictions, as for me. I wouldn't sell now, if I were a holder, that's for sure. I'll keep following them, hopefully will be added somewhere else, not only coinbene.

Experts can't agree as well https://www.fxstreet.com/rates-charts/btcusd/forecast

I would vote for 4K

The number of holders and users. It should be used as much as possible apart from trading to become real success.

For me the current situations looks like a good time to buy. We are risking, it's trading, it's crypto market, everything is uncertain and volatile. Sure, BTC could resume its falls. Momentum remains to the downside, despite the recovery. But we aren't focusing on the coming few weeks only, right? As a theoty, whales that have accumulated Bitcoin outside the exchanges are dumping it on the market to trigger a broader sell and to push prices down. And after prices dropped sharply, they will accumulate some more and eventually push prices higher. So, summing up, no panic selling for me. I'm holding what I have and planning to buy more.

Can only think about people in some financial institutions, who find it scary to try to figure it out. Don't think you'll find anyone with these ideas on this forums)

But honestly, no one likes KYC, and knowing that tracking wallets and fund movements is always possible is one of the limitations. It seems that the more Bitcoin faces financial regulation, the less valuable it becomes, as it may be overlooked in favor of really anonymous coins.

Seems like not so many people were expecting the world’s largest cryptocurrency by market capitalization to fall again so drastically. The U.S. Justice Department is investigating whether it was partially caused by manipulation.

Do you find this plausible?

If we analyze the market in 7 days interval, we can arrive to any conclusions, depending on which intervals exactly to pick. Maybe for now BTC seems more volatile then some of ALTs, but in the long run I don't find these charts to be a reliable source of data for trading or investment decisions.

Some of the analysts say they do not expect the bitcoin price to find a floor until the second quarter of 2019, meaning that the market could face another seven months of downward pressure before conditions improve. So the BTC’s nearest future is not as bright as we would like it to be. What's more, NVTS (Bitcoin network valuation divided by transaction value) is broken below its support level, which is a classic sell signal.  So for now we'll have to observe just how it goes.

It is a risk and we need to accept that. Let's say, you want to buy shares of some real-life company, will you at least check some facts about them? In most cases, you will. But with ICOs it's so often "I was told they are good, so I invest".To get profit you need to do your part in learning as much as you can about a project. And still bear in mind, that it can't be risk-free

Some of the experts believe, that DLTs will have a massive part to play in the future of BTC. It might lead to public open ledgers and their native cryptocurrencies like bitcoin replacing the fiat currency system, and a growing share of the public transitions from government-issued currency to public cryptocurrencies. In this scenario, BTC is likely to go up and up. We'll see if it's true, anyway, to my mind, bitcoin is very unlikely to "die out" or go down a lot.

Bitcoin is showing more stability recently. As I see it, the wild swings that we witnessed in November - December of last year may actually be the thing of the past, the market is getting more mature and its further development will be influenced by cryptocurrency adoption by the general population and general integration of crypto and blockchain technology into existing financial infrastructures

Idk, you need to be sure that they are good. Seems hard to check.

It seems that new projects appear every single day. Do you have your own list of characteristics you find important for a trading platform?

I don't think so. I some countries you just can't legally use BTC for transactions. And on the other hand, PayPal hasn't eliminated traditional bank transfers or Webmoney or Paypneer, for example. The will coexist and may be they will finally face the time when they will be forced to fught for the customers, so we'll all benefit

Would be great to include information on how to recognize scammers and update it according to the data on the projects you review. It's a very good idea, as with the number of ICO going on nowadays people would like to consult a number of resources to get the full picture.
