How? Is it really that simple?
Nope its not simple, study so one can know what she or he could do(or serve as guide

), plus looking back to the market flow and see to predict on what could possibly happen. Reading(learning for reference and making decisions) and predicting is not that simple because you gamble as well.
Yeah, a lot of study is needed in this space and nothing is ever simple. For instance, I got tired of the volatility of the market as I just hated the scenery of seeing my coins and tokens on blockfolio get to huge hundreds of thousands of dollar todays and then before I know it, gets to about tens of thousands in coming months or thereabout. That led me to learn strongly how to trade long term and I believe I am doing better now for a start. Equip yourself with all the knowledge you need to do great in any investment you do and you will always do a lot better.
