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!
I don't like the idea that they should continue to invest every month because they can just hold their remaining tokens during this winter market. And we aren't still sure that the bulls are coming back in a few years because it can also be extended up to 5 years and so on.
Personally, i have be holding some coins over since 2017 ending where the bull run stopped. I bought some coins when the market price was $19,234 hopping that the market price will go up but it never did, so, i decided to hold my coins till the market get back to where i bought exactly before sale. Hold if you can and sell if you are convince to do.
