Misconceptions and the hearsay that they've heard about the business/investment, so instead of taking time to learn things they just push their ways and start their journey, most of those who lean with luck ended up losing a lot, and the experienced that they've got push them away to this venue, it's very important to know the basic and along the way start improving yourself in terms of this investment.
You are correct in that there are a lot of people that go into trading without approaching it as a skill based pursuit. They use chance and feel, rather than adequate enlightenment and plans, which make it gambling. Trading is about discipline, patience and a constant process of learning yet most ignore the step by step doing and run out of money.
A lot of persons actually go into trading with a shallow mentality of thinking it's easy as ABC and some of the cause to this is actually from the frequent flaunting of crypto traders and influencers online which make the art of trading looks so easy as if it's something you can just download a app and then choose any coin or market you get into and wait for it to increase or decrease then you cash out the profit. It's very crazy and so many fail to pass through the right steps involved and end up trading like gamblers and lose lots of money.
