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.
the idea on you are great basis to know the coins is good investment because the porpupose of the project are very important to become succesful the ico become the coin valuable in the coinmarketcap.
for me my idea's to know what is good coin for to invest become profitable i will monitor also the how many coins sold in the market bought by the investor's because if they have many people bought the coins as investment the big possible to increase the price into the coinmarketcap.
