How do you do your own research if the coin is a good investment?
For me, I always look on the purpose of the project, the team behind it, what exchanges is it available on etc. And one of the important thing for me is the total supply of the coin.
I also research if the coin is Proof of Work (POW), Proof of Stake (POS), Pre-mined or other.
I personally rely on fundamentals when I look out for investing in a new coin.
I read the whitepaper, understand what they are trying to accomplish, is there a real world usage of the coin, how is the market reacting to there releases and updates, in short, the market sentiments around that project.
These points gives me a step up regarding the knowledge about the project for future. I dont day trade.
