I know a lot of people who quitted their day job to trade in the cryptocurrency market.
But it was when the market was good.
In this bear market, they're struggling very hard to survive.
So I think the best way to invest is this :
Have a side job, cut down your expenses, then invest 10-20% of your monthly income in the market.This way you never have to worry about gain and loss and surely you have higher chance of getting rich because the market will recover in the long run!
You are talking about 2017 when crypto currency give us a lot of profit and mostly people they quit their jobs and started working on trading and no doubt in trading they have earned a lot of money. But in 2018 was not good years for all traders, especially for those persons who quit their jobs and only choose trading.
But we learn from our mistakes, i also think everyone should have a side job or business where he get a monthly income for their monthly expenses.
Trading is an unpredictable job, which we don't know how long we are going to make a profit and the market situation cannot be the same always, so we should sell the coin when the market is in upwards trend and start investing when the market is completely in a down trend. We shouldn't quit the job for the sake of trading.
