Given the fact that the GDP of US is more than 12 trillions, a 6 trillion capitalization until 2019 is somewhat unrealistic. In my opinion, we could expect this year to reach 1 trillion , maybe 2. In this moment, the total mass of crypto is worth 400 billion (still a lot), in 2-3 months it could climb up again to the level registered in December.

I would buy EOS of them, it could go up this year, their ICO lasts until June.

It is possible to blend this, especially if you are a quant trader in these markets.

Trading, in my opinion, is superior to investing, especially in altcoins. Note that I'm not talking about Bitcoin here ).

I do not see it as a dangerous decision to keep them there, only if you are really paranoid you'll keep them privately.

25%Bitcoin, 25%Ethereum, 50% EOS.

Binance seemed to me a good exchange so far, very fast support, although bittrex has better security measures.

Detaching yourself as much as possible from the emotion of owning the money is the most important. One could had observed the events that unfolded a few days earlier, when many of the crypto owners acted irrational and lost a great deal of money.

Not really sure about XRP, but Bitcoin I think will decrease in value in 2018, this will the year of altcoins, good bet on ETH, in my opinion.

Even Electroneum could be considered a successful one, it's already 16X of it's initial value of 0.01 $, but I do not see it as a being a good investment on a medium and long term horizon.

I predict that in 2018, Bitcoin will take a dip, the money being transferred to a few viable altcoin projects, like ETH.

Seems legit like a mail from a king in Nigeria.

Keep yourself a target in mind, so you can withdraw your investment as soon as you reach it, to minimize the risk that you lose a significant portion of your savings. After that, feel free to experiment.

I do not own any bitcoin currently, only invested in Ethereum and a couple of more altcoins. Given the fact that the possible return in altcoins is a lot more than the one from bitcoin, it is the best bet a small-size investor could make in 2018.

It is a tricky statement, until the volatility craziness phase is done, you can not base a country economy on this type of asset. When the maturing phase commences, it could be a proper hypothesis. 

I have an account at Bittrex for the last 3 weeks, they keep a very low quality customer support. On top of that, when I submitted my documents for the KYC, they delayed my verification for two weeks. I did not withdraw any funds so far.
