It's better to earn real tokens, not fake ones as most of these ICO's are scams and they promise in any method to scam people. I joined so many Airdrops, bounties, but only 2 to 3 paid me and they were in less price. I wasted my time by promoting them on Social media sites.
I suggest you to discover much, but after all these also they don't pay anything for us.

We know so many scam ICO exposed with fake team lately. Just across my mind from defence of scammers. Few scammers defending on scam accusation that some ICO never used team. Also we are not exposing them who have no team on website.
Let me give answer who is like to defend fake team. To be honest Fake team is more dangerous from no team. Because no team already exposed themselves. Investors are able to see there is no team. I will not surprised if they scamed. Because investors known where they are going to invest. So we don't need to exposed ICO with no team as well.

For fake team, they will scamed and divert accusation to others. Becasue they already stolen picture and identity of others innocent people's. So this is a big crime. Investors are not aware about them that they are going to scamed. Because they will see there is a team. If investors  mistakely visit their ANN Thread than he will find great team, nice team, experienced team, potential team many more. That's why we need to exposed scam ICO's with fake team.

There are thousands of tokens on the market but I thinks some of them are really doing well even at this crucial time. What are some of the stable coins you think is doing best now on the market.

When I was reading an article, I came across a disadvantage of bitcoin that stated that there "No Chargebacks or Refunds" in bitcoin transactions. What do you think can be the way forward in solving this problem? Many, regardless of whether you are pro-bitcoin or anti-bitcoin, your interest is in making sure that transactions where currency is involved have a Charge-back or Refund policy.

Below is what the article said on this point: "No Chargebacks or Refunds"
One of Bitcoin’s biggest drawbacks is a lack of standardized policy for chargebacks or refunds, as all credit card companies and traditional online payment processors have. Users affected by transaction fraud – for instance, they purchase goods that the seller never delivers – can’t request a refund through Bitcoin. In fact, Bitcoin’s decentralized structure makes it impossible for any single party to arbitrate disputes between users. While miners take responsibility for recording transactions, they’re not qualified to assess their legitimacy.

Some newer cryptocurrencies, such as Ripple, have rudimentary chargeback and refund functions, but this feature has yet to be built into Bitcoin.

A lot of people said Chinese Ethereum for NEO. I searched a lot about NEO , then I bought some NEO at 0.0085 btc. But it dropped at 0.0072 now. I know the market is down but NEO dissapointed me. What do you think about NEO for long-term investment ?

Enough of people just creating tokens just for the sole purpose of trading it in exchanges and making money after the ICO. In order for a token to survive or stand the test of time, there is need for it to have a working product or service it directly supports. This is what a lot of tokens are lacking today.

In my opinion, any token to be created should bring in something new. It must be a token that will add value to the society and not just for the purpose of trading it in exchanges and cashing out money.

If we actually want cryptocurrency to survive and appeal to the ordinary people, then we must create ONLY tokens relevant to the society's needs or solves at least a particular societal problem.

It takes longer for all countries in the world to accept or legalize Bitcoin and crypto currencies in general because not every country has achieved the same technological progress in the world and not only that. The excess of crypto currencies in some developed countries can be a disadvantage for less developed countries.
