Thanks for all the advices ! I started to have a look at the market, I randomly look at some coins and got some surprises. For example Telcoin, I watched at their channels and seems they ban all the people that ask questions about the coin !

No need more to know this coin is not worth it haha.
Is this serious ? you only asking about the coin and banning is what you got ? it's not fair for a investors approach , people tend to ask frequently Because their Money is at risk here.
I heard a lot about Neo too,
You can start learning neo by following their graphs , starting 2017

Thats best way to spend Money inside crypto market , Diversification is what you must do so at least there are several chances of gaining while some may lose.
