You know it very well, I guess you ever experienced the same problem, @Domithra. 
Especially for airdrops, I think it has been worthless and not recommended to join. I never join again airdrop program since I experienced some scam airdrops. It is easy to do, but it is also easy to get nothing. I suggest for everyone to choose bounty programs, it is much better than airdrops. But you still need to analyze the project before joining. Not only airdrop, many bounties are scams and fake.     

Very good idea to tokenize the fitness band. I see you will have a product, GYM Rewards app. I guess you are planning to function the GYM Rewards app to support fitness band. I want to know more about your GYM Ledger project. So, I have some questions below:
1. What is the function of the app related to supporting the fitness band?
2. How important the GYM ledger tokens for this project?

However, I really appreciate GYM Ledger project. It is very potential to develop more. So, I hope by providing ANN and Bounty Program here, many people will join your project.   
     

I think everyone has started to care about Crypto. starting from government regulations and bad news. won't this give great popularity to crypto? just relax they just want to buy crypto at a cheap price.

Yes. The negative issues make people curious about cryptocurrency, then they try to find out the truth. Some of them potentially stay to start working on crypto after they know many advantages of crypto. I am also not afraid to see many coins now, it actually makes the market more alive and dynamic. We shouldn't be panic and hopeless with the current market situation. A new crypto era has just begun. 

In my view, for investment, the top 3 altcoins this year is Ethereum, Litecoin, and EOS. I don't state that only those coins are the best altcoins in 2018. There are other best altcoins such as XRP, NEO, ADA, DASH, BDG, and also XLM. We also should take attention on these coins.     

In my view, here are the top 5 crypto exchanges in 2018. I choose the exchanges based on their reputation, popularity, and advantages. Here, they are:

-Binance
Binance is one of the most favorite and popular crypto exchanges around the world.
-KuCoin
KuCoin has a good reputation, provides easy and hassle-free experience with various cryptocurrencies.
-Bittrex
Bittrex makes everyone to trade in large numbers of trading pairs with all the major cryptocurrencies.
-Bitfinex
Bitfinex is one of the famous crypto exchange platform, makes you to trade effectively and conveniently.
-Poloniex
Poloniex provides more than a hundred cryptocurrencies, it is an important advantage for trading.

The first thing that newbie investor should think is about the mental and knowledge. As an investor, you must be more patient and ready both for profit or loss. Then, never try to work in trading or investment without sufficient knowledge. When you decide to sell or buy, you will do own research or observation firstly. This research or observation needs your knowledge to get best result. That's why I said you must think about knowledge at the beginning.   

Lol.. I think it is pointless. Talking about imagination won't bring benefits, but it is okay for a little entertainment. 
Umm, many coins are hard to become popular because of too many similar concept and ideas. A low capability of team and wrong marketing strategy are also caused the problem. So, it is very recommended for developers to think about it before planning an ICO project.
