When the last year bull run was happening my friends believed in cryptos and most of them left their job to focus on cryptos but since the bear market started and eat dip into their asset, most of them thinks it's a scam now, But I keep telling them that things will still improve that patience is required. A lot of people have lost hope in cryptos already.
Leaving your full-time job to concentrate on crypto is always going to be a very tough option. I know a few people who landed in trouble after doing so. But then, I know one individual who became super-rich after doing the same. All depends on your luck...
