if you know that coin goes down more of course you must sell and then buy whereever you think this is dip. but hard to do :/

you can know about that coin is gonna worth or not if you know how pick valuable bounties. i search to much to before join in any bounty.

Ithe trend reversal will occur very soon and bitcoin will start its growth again (like right now), many do not believe it, because they already disagreed greatly in this, but still it seems to me that this is quite normal.

I suggest that you too should hold it, anyway it's just the start of the year. Many predict that by the end of 2018 altcoins will go higher much as expected. But if you're uncomfortable with the situation, you can sell just half of it and see what the other half will do.

Currently because of the fact that transactions are slower in bitcoins, there is a sudden increase in the price of ether but maybe the hike is temporary. imho

this market is risky when you invest in there is a little chance that you lost most of your portfolio

in my opinion you should find coins which is strong leader and team and lots of people who believe that coin with all their hearts. for example i love wanchain and believe she will fly soon.

you should buy altcoins, because altcoin is an investment which give you a good return. where you can receive profit in the future by the use of it.

Sure. ripple has potential , you can hold it for a long term. It wont make you dissapointed..

from yesterday the part of Ethereum I'm holding for a long-term investment, and the second part for buying and selling various coins.

Bitcoin is coin that allows entry to the cryptocurrency world, Ethereum is main ICO platform. those are big guys from the begining...

Best bet would be for you to check out the coinmarketcap,, take a look at the coins that excite you and what important problem or challenge are the developers looking to solve with their coin.

So what? Then it goes up and up. Every time cryptocurrencies have crashed, they have come back up. Over time less projects will rise following a collapse, but that will show market maturation.

 if i participate to those ICO's bounties  make sure that this will be going pay me until they end of ICO.

I realized that when investing in a company, it's good discounts, plus you give more coins, well, if you did not give away coins for free, they would not be worth the price.))

Many people invested in it and all of them gain a profit. I think some people are jealous and they call ethereum a scam.

 lot of ICOs going on and very little innovation by some projects teams, we are going to see a lot of tokens being delisted as value plunge to near zero.

In my opinion the current bitcoin price is very dangerous so you shouldn't buy now. Don't be worry because bitcoin will go up i think there are no risk in investing bitcoin in uptrend.

i think banks are safer for now , bitcoin brings in more profit as they increase in value because they are like assets but the safest way is you can allocate some amount into crypto and some into fiat, to minimize risks..

you can be a emotional person but when you trade, you must separate you emotions and your movements.
