Why you missed trading on that list? I am in crypto trading for more than a year and making good amount of money with it. I am also investing in multiple coins during crowdfunding and holding them for atleast 6 months to get maximum profit out of it.
Trading is a great way to increase your coin stash and generate some regular income. But it cannot be stressed enough: Most people will lose money from trading. It's generally understood that trading returns follow a Pareto distribution, so 80% of traders are losing money to the 20% that are profitable.
I've done well over the years, but the simple truth is that most people aren't cut out for trading. It can take a real psychological toll on you if you can't deal with the volatile swings and prospects of losing streaks. Every trader needs to be able to take repeated losses, no matter how good their system is.
