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.
basically the same, that is looking for the best opportunity to invest it is necessary various analysis of the developing coins, which coins should be selected and the potentially good in the future, see the history of the coin on the market whether the behavior, high-value or able to survive amidst the price storm that changed? it all goes back to a trusted source by deepening the knowledge of coins and its marketing and its association with good and successful corporate projects. a good coin for me that is more dominantly chosen and used by trusted companies. it needs to be known by digging a lot of information thoroughly.
