If you're already having huge capital for investment, maybe you can have that mindset losing what you can afford. Same with the friend of mine who quit his job, unfortunately the money he saved didn't prosper and eventually got burned in trading. Without proper knowledge on cryptocurrency trading, everything turned down and got vanished when trading without any concrete foundation of skills.
It is not a good idea to leave your job for trading because trading cannot give you money always but it can make you distress so I will suggest that you don't leave your job for trading and if you have saved the amount but have no knowledge then saving that amount for something more time is better than losing it in trading due to lack of knowledge.
Most of the people are so greedy that they don't investigate trading but want to get the sudden profit so they lose a huge amount of money in a day because they don't follow the rules and have no command of their decisions so at the end they are just empty handed.
