Or is there any other way so we can check about respected crypto might be it'll work?

You definitely have to do your own research as no one is better to protect your money otherwise than yourself.

One of the few key factors that you can spot a scam is by looking at
- the dev team. Scam projects may not show any faces of the team at all. Or even if they do, they will not give any more links to verify the picture in the website is the real team. Check out if the dev team do also post on their respective social platform about their involvement in the project.
- look out for over promising project. if an ico tell you that you can earn 100% within 3 months, turn away and walk off. If they can do it, they wont even need you. They can do it themselves and within 2 years, they can already became the richest man in the world. 3 months x2, 2 years = x256, so just gather a million or so, and you will have close to a billion in 2 years.
- look out for grammar mistakes, it is not 100% true but a lot of scammer has shown that they do not put in the effort so there will be a lot of grammar mistakes in the website, whitepaper etc.
- read through the whitepaper, gather all your thoughts and doubts, challenge these questions to the dev team in telegram or email. If the dev never reply, just dont bother and if they reply but they cant answer your questions well, you also can consider to strike off this project.

Having to work with Chynge, i am curious to why they did not adopt eth and end up taking up Stellar. It was after diving into Chynge that i find out more about Stellar and how amazing it is.

I also have the chance to recently saw one of the dev demo live during a meetup session.

Stellar already can reached a 1k tps and can even reach out to 2-3k tps during stress test. They are also impoving on the stellar coding etc.

Until now I've also never received airdrop from Stellar, and I think until now Stellar is hard to get airdrop, and we hope for the future to get more airdrop from Stellar.

The different for stellar wallet is that you have to activate it before you can receive anything, even stellar tokens, xlm.

So you have to check that the stellar wallet that you have registered with all these airdrop, you will need to have 5 stellar tokens (xlm) inside it before anything can happen. Also do take note that some of the airdrops, you also need to add trustline in order to reflect in your wallet.

Friends!! I want to open a very important topic, not only for me, I think for many new participants and those who are just starting their way in the crypto-currency world. The theme of learning and the basics of blockchain and cryptocurrency is the main thing that a person should understand when coming to this area. But also earnings are of great importance for many, in this difficult time. It would be great if you share your experience of earnings, methods and links to training resources! I hope this topic will help a lot of users) Thanks

it is great that the community here is friendly and also equally important, they are lively. So we have constantly interaction going on at different sections. You can ask about anything and there will be helpful advises/answers given.

So far, the only obvious benefit is claiming a bigger stakes/shares in the signature bounties. As for the other bounties, ranks does not seem to play a part.
