Dude, of course, it is the last "Black Friday" to get cheap crypto! If you are investing for several months. If you already invested, I would wait several weeks before.

The market will be a lot better with only quality projects used., don't worry about this. And by that time the ecosystem will be a lot more important than currently. 2 Years is the minimum, I am looking for.

Privacy coins will get more attention compared to others, Horizen, and others will see their community increasing, + popularity.
With all the regulations coming a privacy coin + decentralized exchanges are the winner combo

Awaiting for better days, no way I am going to sell something currently unless crypto is the only way to pay.  Some traders are still making profits and some increasing their bags, everything is the same but at a lower price.

It depends on how long you're planning to invest. These days someone investing in cryptos should do it for a 12-24 months minimum period. Shorter than that is a risk for a loss because I don't think we will have a "good 2019 year" but later in 2020.

Privacy coins will be more popular than ever. I advise you to hold a couple of bags of different privacy coins like Horizen, XVG, Moenro... These coins will be popular in 2019 and all of them will boost their price.

If you have a consensus yes it is viable, you will always have people not agree, a different opinion, different interest. But still, it is viable as long as we have an agreement with each other, a protocol we agreed to follow while using the crypto.

People have different needs so different cryptos fit better in their cases, I see 4 types of categories coins in the future.

-The fast coins
example: Ripple

-The cheap coins
example: Dogecoin

-The privacy coins
example: Horizen

- The SoV coins (store of value)
example: Bitcoin

People are currently learning a good lesson that BTC shouldn't be considered for an investment but shall be used as a currency. And they are learning it in a hard way. Use your bitcoin to buy or sell, that's the main purpose of BTC.

Poloniex is horrible. I didn't know some people are still using this website. Move on to another. Binance is maybe the most popular currently, Bittrex is another, just look around.

Anonymous or not, do not trust anyone on the web, no matter how good the story is. Especially when it's about money.
I wouldn't trust an anonymous team but some may be legit. It's just better to erase any risk on your investment.

Horizen has a real team behind, they do have a presence online and not just a bunch of photoshopped photos like how the ICO projects do.
Horizen representatives often appear either in public in a conference or meeting or on videos, either for an interview or something else.

An altcoin with a good potential is Horizen https://coinmarketcap.com/currencies/zencash/
A privacy coin using the Proof of Work Equihash Algorithm with currently over 17000 nodes which is excellent. They have a huge team of 50 people working non stop on the Horizen platform. 50 people are huge and need a lot of coordination to make a team efficient. it brings together a lot of knowledge and experience accumulated.

Too bad a centralized currency take over the second place on the top 100 decentralized crypto currencies. But I know it is not the first time and usually doesn't stay longer than few hours. But we need several days or weeks before claiming XRP take over ETH.

No, scammers don't affect the price, otherwise, the dollar would have collapsed a few centuries ago, and ETH would have collapsed every weeks too which didn't happen.

Don't buy the FUD, buy cryptos instead. Use this opportunity to buy cryptos at a cheaper price and enjoy the Black Friday. Everyone can currently make a quick short profit, don't be lazy or you will end poor.

They all have their + and -
Bitcoin won't be replaced by another altcoin but people may prefer to use another one for several reasons, privacy, Tx fees,...etc. You maybe prefer Doge for a cheaper transaction fee, Horizen for a better privacy than BTC or ETH for a smart contract, and so on...

Make whatever you like is the most important, but I wouldn't rely on a whole career in the cryptocurrency world. If it's really the path you want to follow, be sure to have a plan BTC because you never know what can happen in 5-10-15-20 years....

The blockchain won't really help the economy but rather the companies. They are the one that will take the full advantage and they will save a lot of money. A bank firm will easily be able to save about 10% on the transactions costs, reduce by 20% the insurance operating costs. After a year it could be  several millions saved. Of course, don't expect to see then the prices decreased

People shouldn't rely on the ranking from coinmarketcap but the white paper. And Yep, if the crypto has a good white paper why not? I did it with Horizen, it wasn't in the top 100, 1 year later it's on the top page. But as I said the project itself is what matters. The tech, the tem, the WP,...
I did with few other coins as well Ark, XVG
