There are so many New ICO's these day ? Is that safe to invest in ICO ? any 1 invested in 2018 ? 2017 was the year of ICO's but is that still safe to invest ? or how to know which ICO is good to invest ?

I does not think anyone can be sure whether any ICO is good to invest in till it is out in an exchange but you can increase the chance of spotting a potential ICO through various ways like research on team members and their product MVP etc.

Trading is like an addiction, but this bear market seems will be very long. Bitcoin is going to under 4k USD, ETH is now 110 USD, Almost 80% coin fell down. I can't make profits at this moment in trading, Because after getting a little bit of profit, the market again goes under, then another coin eats my profit too. What should I do now?

I advice switch your trading to a long term approach don't be a day trader in bear market as crypto market is decentralize and even if you are able to make money out from the day trading but in the end you still need to cash out in bitcoin. So it is of no point to do day trading in bear market.

Hello, however I am very interesting in engaging into trade of cryptos. I am looking for some advices on how to learn the trading process first and then how to start trtading. 
Thanks for all the answers in advance!

Firstly i just want you to be clear that i am also a novice as you maybe with a bit more experience, i will share how i learn the art of trading, since crypto offers a section which no other investment instrument provide which is bounty hunting you can start from hunting and gather the right knowledge in choosing the right bounty first then when you have some capital then you start your trading. At the same time while doing bounty hunting you should leave some time to study on various aspect of the market for example the candlesticks and how the market behave.

Obviously, from all the time high of 2017 to the worst bear run that grip the crypto market in 2018, many individuals and organizations had concluded that crypto is a bubble ready to burst.
Now, i think crypto has proven itself to be legit invention and ready to pump. What do you think?

Bubble or not bubble, legit or not legit as long as crypto is able to serve its purpose to the crypto adopters who will really care what are they in the market.

I am sure if crypto is able to survive bank attractiveness will definitely be affected but we cannot really say will it be good or bad. Crypto survival can make people see more carefully on making investment and in the long run more people might come in crypto market or stay away from it but go into bank managing their portfolio.

Some governments are starting to embrace blockchain and cryptocurrencies and others are literally closing the doors to this technology. Do you think governments will continue to fight back against cryptocurrencies and decentralization?

From a normal point of view if something is a threat to you you will start to destroy it isn't it? Same goes for crypto and government as long as the crypto space will not threaten the government in any way living in harmony together should not be a problem.

We believe that crypto is a future money but why is that so many coins are dumped in the market since is a future currency, is still a future money or temporary currency.

I will remain an open mind on whether can crypto be the future money, before something valuable is out most probably it will need to go through a lot of down period and crypto is no exception as well.

I do not intend to give news that is not true or only an issue,
but if I look at market developments and btc development charts, crypto will be improved in 2019 and prices will return to be better,
at least in mid 2019 until the end of the year.

I also think that in the mid of 2019 crypto will be able to do something about its price but that is just my personal opinion and might not be true.  Crypto is just going through a restructuring stages do not be panic.
