I would turn the question:
Decentralized or centralized storage?

The answer is definitely decentralized.
The whole blockchain and cryptoworld biggest advantage is decentralized, no one should be capable to steal your coins (except of your fault if you let hackers to get your private key), but if you store your coins on an exchange they can do it anytime.

So far infrastructure coins were the best investments. EOS, Icon and lately my personal favourite Zilliqa (which is the best one out there nowadays IMO). However, today you can find a project which promises 1M tsp in every corner... time to move on and focus on real projects, blokchain infrastructure is getting ready soon (wait for 2nd 3rd generation blockchain to release mainnet).

I think that after the decrease of prices, there are less, new, banning countries...When the BTC was kicking 20k, there were many news about banning countries, restrictions, rules etc.
Nowadays, it is chilling.
After stabilization of the crypto market, prices will rise again. But I think that it won't be such a huge jump like last year, so the regulations won't be so strict.

Whitepaper is a necessary document to have. All ICO need to have the whitepaper.
But it is not a guarantee!
Even if the ICO has the whitepaper, it can be a scam project.  As you can read / hear everywhere be wise and don't invest into projects without researches, enough information.

Yes, I do, but it is necessary to do it carefully. Your own, private identity data are really sensitive.
If somebody take advantage of your personal data and use it for projects, deals or anything else, it can be really dangerous.
So be careful, read about the ICO before you do KYC or invest money.

Sure, it is necessary to have a successful, real product or service behind the ICO. It can prove that it is able to survive in the crowded crypto market and the management won't disappear with the invested money.
It is really cool, if you can invest into such a project.
Sometimes a good idea can be also successful, but in my opinion a real value is better.

If we are talking about only 2018, maybe ETH was the winner of currencies. But I think we should think in long terms...If we look the overall crypto picture it is not questionable, that Bitcoin is and will be the biggest and most successfull crypto currency.
The whole crypto world was based on BTC and nothing can change it.

Become billionaire, rent a luxury apartment in one of the most beautiful islands and relax there for a few months. In the meanwhile continue the cryptocurrency/blockchain learning, analyzing the market and watch how my investments make me 5-10-100x returns. Go Zilliqa Go!

I think we need to break 6800 level to confirm that we are currently in a bull run. However I do not expect a long run would be surprised if we could go 9K+. We need some volume first and real use cases, regulations and stability, lack of hack and other bad news to see 20K again.

I think the most popular platform of cryptos isn't Facebook..The people who are trading BTC or other coins, they get information from crypto related sites and not from Facebook.
It is true that FB is one of the most popular way of advertising, but it is not the only one.

On the other hand, Facebook would like have own crypto currency, so the message of banning ads isn't too trustworthy.

These two facts can explain, why haven't these news effect on the prices.

I think that the whole crypto world is still in the egg by us. But there are much more meet ups regarding blockchain, bitcoin, altcoins etc..
Luckily, it is not banned by us and I hope that it won't 

I think that Ethereum is more successful than Bitcoin during this year. But it is just half-time
Many forecasts say that it will above 10k till the end of the year.

However I think that the raise of ETH was bigger surprise and success than the way of BTC.

I think that you can learn a lot from this forum as well. But if you just write your questions in Google, you will find many sites with useful information, lessons, videos. If you have time, before investment you can talk with the managers of the ICO and ask them about some additional information.
It is always important that do your own researches because there are always sites with false, invalid information and these can mislead you. That is why it is better to use more sources.
It takes time to learn it, don't give up after the first problem or scam project.

It is just like in the real world... There are many-many startups, which come up with a good, excellent idea however the management will fail in the real, business world. And also there are big multinational companies which can bankrupt even after decades.
The reason for fail of ICO can be different, but it is not unique and special behaviour of the ICO.

It depends on the coin...If I think that it is a profitable coin, the company and the team is impressive, the technology and the idea is demonstrative I will keep my coins and wait for the increase of the prices.
If I think that after the ICO the price will fall and it won't survive in the crowded market... I sell my coin in a short time

It can happen, that after ICO of a scam project the 'managers' just disappear with the collected money and they won't give you any tokens... It is the risk of the bounty program, but you should be aware of this.
Best is if you speak with the company before advertising their ICO. More or less you can decide if it is scam or not..
It is worse if you invest into scam project. Than you loose your money, during the bounty you just loose the invested time.

I dont think so..ICOs wont die in 2018 even in the nesr future. Behind the successful ICO are well maganged conpanies, with real perspectives and goals. These companies will not disappear just because some ICOs die or because of scam projects.
If the whole crypto world die,than could it happen, otherwise i can not imagine any reason for it.

I hope that it is just a temporary period. Most of the analyses go about the rise of the BTC and tell it will hit the 10k in a short time.
My personal opinion is that the BTC bubble was ended by the 20k price and now it is stabilizing and making the way back. We just need to be patient
Hopefully, until this moment the market will be controlled, the fake projects will stopped and the valuable investment will establish a new perspective.

No one can predict the future of the BTC, but I think it will increase soon or later. So if you want to invest, do it now
There are a lot of posts, articles about scam projects in the crypto market, but I hope it will change...The control has to be implemented, otherwise nobody will invest.

After this clearing of the market, the prices will stabilize and grow. BTC

If you are doing bounty program, there are 2 main options at the end of it:

1. The ICO is done, you will get your tokens within a short time.

2: It is a scam project and the people behind that will steal the invested money..There won't be any tokens, profit.

Even though if the project wasn't a scam one, your tokens can loose their value. Because the ICO isn't equal to the success of the company behind the ICO.
It can fall after the ICO, but it can be profitable too.. its almost 50-50% . It depends on the managers behind the ICO, on the idea, on the investors etc..

So if you are not sure about the future of the ICO, sell your tokens.
