They seem biased to me. A friend of mine who's doing an ICO told me that they paid 10ETH for 5 quality ratings and that's that! I noticed that some ICOs with good project, team, and good social media presence are struggling with getting good reviews.

With all that said, should it still be a factor to look at when investing in ICO?

please anyone guide me.I want to buy cryptocurrency.

I want to know what you think, what affects the bitcoin price, so we can find out when to sell and buy bitcoin, because now the bitcoin price drops again 

How can I earn cash without investing? Can I earn a thousand dollars without investing or buying first?

Due to the increased popularity of cryptocurrencies, there has been an increased number of scammers both in terms of ICOs and in social media. You would find "official" representatives that would "propose lucrative deals" in the name of the legit company. There is only one result as a consequence - you losing your assets.
Thus, always keep in mind that real official channels of communications work. Also, if you see those posts in social media promising returns without a legit background (a.k.a. a full-blown platform) is a sure way to lose money. Creating bots on Facebook, Twitter, and Telegram is quite easy these days. Make sure not to repeat mistakes that others made before you https://www.cryptocointrade.com/
Not to mention mining pools and app scams going on right now. Some of the Facebook groups that were excellent in terms of trading discussions now turned into scam marketing sites.

Some analysts are of the view that Bitcoin Price could reach a peak in December that is double the price now?

It looks we are stable again. Are we going to go up from here or back to bear market.... What are your thoughts?

Most airdrop and bounty programs are based on the ERC-20 platform. But you see that. Severe downgrade ETH will greatly affect airdrop and bounty. I need some advice now

Trading or investing in the Crypto market is a psychological battle for yourself. Securities investors often say that investing in traditional markets requires very high disciplinary action. This demonstrates how they will control themselves for the volatility of the market. How can they eliminate the wrong decisions that most people still make and adhere to the strategies they have set.
If traditional markets require discipline, the Crypto market requires resilience and a sense of steel. The Crypto market has tremendous fluctuations in comparison to other markets in the world, in this market the preparation of emotions and keeping a cool head for a trader requires a lot of practice.
Here are the things you need to remember and when you need the best psychology for a Trader to cope with market fluctuations.
Do not try to catch the right market!
If you are really lucky to have a source of money to invest in when the market goes down, it can be a good time to start making money. Many people keep thinking about adjusting the market as a "Flash Sales", and always try to think of getting the bottom right of Bitcoin to make the most profit, but then you will notice the bottom of the day. this is the peak of tomorrow.
When you look at price charts, look at the price of coin straight into the pit, you ask yourself when it will stop the price drop? You are catching yourself to catch the bottom of this rebate. Getting the bottom means you are trying to trade in a bottom of a downtrend trend. It must be emphasized that it is really difficult to get the bottom right in a downward trend, which is just like posting a knife with a high velocity.
If you still insist on capturing the bottom of the rebate, you are missing out on a lot of better earning opportunities. There may be times when the secret is simply "ONLY, ONLY AND ONLY" until you have identified a trend reversal of the market. Many people lose more when they keep their view on having the most profit when they catch the bottom. From time to time, you intend to place orders when thinking that the current price is closer to the bottom of the market than waiting to determine the right trend.
Do not sell your coin when looking at your coin soaring!
Many people have done this, the general psychological tendency of the market. Many stories share the same plot, and each time you see a coin A rising drastically, you start to sell your Coin B and immediately jump into Coin A. The psychological effect is called The FOMO is a normal fear of human psychology but is really dangerous in the Crypto market.
Do not stare at the Chart all day!
Those who have just entered the market, will spend a lot of time to "charting". Looking back, if you are honest with yourself, how much time you wasted. You spend a lot of time learning and learning the knowledge and application, but also spend a lot of time aimlessly to look forever into the computer screen with the red blue.
Sometimes the best thing you can do is to put a little order, walk scattered, trust the strategy you set, and remember "IF YOU DO NOT COME BACK TO YOUR STRATEGY, YOU ARE SURFING IN THE MARKET "

For those of you traders, please be careful with fake exchanges, because I found a VERY SAME exchange that makes no difference at all like the exchange on EtherDelta, the fake exchange link that I saw I got from my Gmail inbox, which message it was contains about giving tokens like AIRDROP, and there I am given a registration form link and in the form there is a fake EtherDelta link, and this is the link http://EtherDelta.website, and this is the original EtherDelta link https://etherdelta.com/. There is no difference at all in the two exchanges, the images, features and others are exactly the same, so please be careful.

Secure your private key, secure your wallet, do not easily believe things that invite you to get rich instantly, do not easily trust advertisements, because crime is not just at one door, who knows there are many other fake exchanges, therefore be careful.

Now that more and more countries are starting to go cashless (http://www.bbc.com/capital/story/20180427-does-a-cashless-society-benefit-everyone), is it possible that we also start converting to cryptocurrency? If that happens, what do you think are the advantages and disadvantages? Paying virtually is very convenient for me as I do not have to bring cash and it prevents petty theft but what is the disadvantage?

It is needful to say that before the completion of a magnificent building, it starts from the foundation, therefore, to excel as a crypto enthusiast you must start from the foundation, which is through the acquisition of knowledge.
I will not deny the fact that learning is a continuous process, but whoever is coming newly into crypto, should try as much as possible to learn first the rudiments before venturing into any aspect of crypo in order to avoid making costly mistakes.
What you already know cannot be taken away from you...
So, start from the foundation today and get the best from the crypto space.

Bitcoin is truly a treasure for someone who achieved even a single piece of it.
