It's a very brave management, I hope you can be lucky in the two crypto trading and don't regret your decision
Brave it is and if the things he have said is true then good for him. Just don't like the idea of quitting our full time job for this trading crypto thing where uncertainty is very high. He might regret later his decision.
Trading generally is for those that can take risk in which the risk can really be worth it in future and for one to really be full time trader, one must definitely quite any job to concentrate on the trade because it requires lots of attention and concentration to be able to trade successfully.
Although before one can confidently quite job for trading, the level of understanding and skills developed must have been so high, otherwise the person would just be shooting himself in the leg by quitting without deep knowledge. Like me now, I am very good at trading but cannot dare leave my job as I still make trade mistakes sometimes.
