It becomes very sad and unfortunate when you toil for several months for tokens by participating in a bounty program and turns out to be a shit coin or a scam project. I believe most of us here have been victims once.
The fact is, there isn't any 100% working strategy to detect the authenticity of a project. The best you can do to help yourself is to do a research on the project. Study the team members and try to figure out if the team really possess the credentials which they present on their whitepapers and websites. Check out if the advisor chosen for the project is really on board with the team by cross-checking from his tweets on twitter about the projects.

There have been many airdrops in the ecosystem and sometimes they bid KYC before you can join Do you participate in those airdrops. As for me I don't participate in it because I have seen that all airdrop coins are shit coins.

I heard some of my friends if they has seen altcoins and its benefits earlier they would have stopped schooling and then only focus on it. I want to know that can someone make a living with only altcoins? and how can it be done?

I believed that altcoins will survive a long time we can't say that today because all know that bitcoin works is more popular compared to it. All things needs time and i think altcoins need that too so we need to wait until this will go up higher. I just need your ideas what's your thoughts on this topic.

With increasingly positive voices coming out in favor of Bitcoin, it remains to be seen whether it will actually repeat what it did last year... from $900 to $20,000 - Bitcoin's historic December 17, 2017, price run. What about you, guys, do you think Bitcoin will increase in value significantly until the end of this year? Or will it remain around the levels we have these days? As of this writing, the price of Bitcoin is $6,772.32.

I do not understand what happened to some altcoins, I know that when correction, red altcoin dominates the crypto market.
but when the bitcoin correction, there is still altcoin that has increased and rises significantly. what factors make altcoin rise when bitcoin falls?

One strategy that works best in times of fall in the market is to remain calm, and not allow yourself to be blown by panic. Just hold the tokens with large caps and even if possible, buy more tokens and hold. For some coins like Bitcoin and Ethereum, it is always certain that whenever there is a fall, there is definitely going to be a rise.

What will you do when the market falls?
