A large part of my portfolio hold for them, about 80%. So that my profit increased X10 for six months. The market activity invest 20% of the Deposit and expand the portfolio. Basically this is a promising coins such as wgr, bnt, mgo.

Overall, the portfolio consists of the top coins. But I would add to this list of promising Altcoins with high potential in 2018. WGR, BNT, EDG. They are inexpensive, but have already done X10. Further more.

I think, this is not last drop bitcoin in this year. And those who managed to purchase alts, now have a nice profit, part of which can be fixed.
BTC before New Year fall again, to about 10K. (IMHO). And in 2018 will continue to grow.

Even now, there are all chances to become a millionaire with altcoins. It all depends on your chosen coins, the amount of investment and term.
To cite one example. This spring bought an altcoin on the EDG.., 662 coins for$ 8. For six months the coin has increased by 17,000%, or 170 times!!! And continues to grow.
Is now really the best time to invest in cryptocurrency. Be patient and choosy about the coins.

Now it is best to withdraw profits in cash to buy when the market falls. Because bitcoin right now is not stable. And there is a risk of greater drawdown before the New year.

Now, invest in altcoins, I would not. You need to wait. I'm sure this is not the bottom and bitcoin will drop lower (8-10K) before the New year and drags the alts. And once that happens, stock up.

All is not lost. Notice how quickly recovered all of alts. I think next week we will see something similar. Most importantly, do not be greedy and to have time to fix the profit before the coins will subside.

I guess this is start of Bitcoin correction before the new year holidays. And it will fall to 10 to 10.5 K. Of Course, this is just a temporary drawdown and Bitcoin will continue to grow, but not so fast.
Now it's the best time to buy alts. If you are afraid to take risks, buy small parts. Then, in the case of further decline, you will be able to buy another.
Choose a strategy for investing and clearly follow it.
Oh, and make sure you make money to buy bitcoin. This might be his last drawdown to this level.

A very good amount to start investing. If you are looking for a hint where to invest, here you will not help! I would advise you to consult a professional crypto trader to optimally shape your portfolio.
My Deposit is distributed in several directions: a part of bitcoin (30%), some in altcoins (50%) and another part (20%) bring in cash.

The amount is really small. But if you know what to bet, you can increase the profit several times.
Recommend inexpensive and promising coins - Wagerr. Now it 0,335$. In the summer I bought it for 0,07$ for them. Today he brought me +360%. But the main events are expected in mid-January, 2018. I think you should not split such a small amount for a few coins, as I will have to wait very long for profit. Bet on one thing. And gradually increase its portfolio of new coins.

I recommend to those who actively trades! Everyone be careful on the market now. The exchange is very much growing in the past few days amid the calm of bitcoin. This may be the beginning of a new year of fixation. So I would recommend not to buy any altcoins now and gradually begin to take profits, withdraw in BTC, USDT, USD, wait for the subsidence of coins and buy again.

I invest with crypto trader. Get insider information on the signals and invest in promising coins. Also, you can find a lot of useful on the bitcointalk forum.

I had a similar situation in the spring when I bought 2.5 Btc altcoins. And it was about 2500$. Today I have only 1 Btc in altcoins. But now it is already over$ 19,000. And I gradually put part of profits into cash and USDT for further investment into the cryptocurrency.

You bought eth for 159$, and now he's 718$ and continues to grow. I see no reason for concern.
Congratulations! You have earned!

Stable altcoins is the most liquid and promising altcoins in today's time.
Stability and development depends entirely on the attractiveness to users, because this currency is not supported by anything.

The main criteria that determine investment attractiveness of any  altcoins is: its attractiveness (ease of use, speed enumeration, etc.); market prices; the dynamics of growth rates (changes of price altcoin for a certain period of time); the market capitalization.

Based on these criteria, you can choose the most stable altcoins specifically for yourself. And you can distribute your Deposit into equal shares and invest in the Top 10 altcoins.

And here is the answer to your question. This article explains why the main rival of Bitcoin is not Ethereum.

It all depends on how long you want to purchase coins. If you want long-term in - DASH, ETH, ETC, LTC, ZEC, XMR is the coins that slowly but steadily increase.
If for a short time - in the WINGS, now is a good entry point. They have a December release beta version of the platform. Well, of course, don't forget part of the money hold in bitcoins. As well as to capture and withdraw profits.

As for me, the best Altcoin 2017 was little known alt EDG. In the spring of 2017 I purchased it for the remaining 8$.
This coin gave a profit of 10,000% in a few months. So you don't always need to listen to what the media say.

Here's what you should remember not to fall for phishing sites!
1.Carefully study any messages asking you to provide personal information. 2.Satisfy such request only after verifying the trustworthiness of the site. 3.I recommend not to click on the links provided in the messages, and try to access the sites and organizations in a separate window.

Data storage security with Litecoin, leaves much to be desired. You can not say about Monero.

No wonder that the leader in security operations is considered, Monero. Cryptocurrency is becoming more popular, regardless of the purpose of the operations. Information about transactions in Monero securely hidden.
I would advise you to keep in your portfolio both coins. Never know which altcoin will give more profit.

Interviewed media experts evaluate this increase and explain it with different reasons.

Someone said that the better scales litecoin compared to bitcoin, and looks convincing as a payment system. Others describe litecoin as an investment that caught the "tailwind" in connection with the arrival of new investors to the market, so the attention paid to bitcoin in the last few weeks was a turning point for all other cryptocurrencies.

Anyway, buy litecoin now, I would not, and waited for correction.
