When I have some coin wallet or market showing RED signal I can't stop myself to buy a coin. But maximum time price goe's deeper. Lot's of time it's happening for me, maybe the same story happens to you.
So let's start discussing what factor need's to check like Volume, moving average, price history etc..
The marketcap of the coin and what the whitepaper says about the coin is the most important factors of the coin because I need to know what the coin is about before purchasing it.
