Both trading and investing are the same way and destination to get much profit but have different system how to get much money with bitcoin and altcoin, with trading we can earn much money every day and investing could earn but need waiting for long term.
Yes, I would say that its best for everyone to do what they are good at so they dont end up losing their money (well, people will always lose for others to win). Trading is cool and thatd due to several reasons of youre trader and youre really good at it to the extent you now became a full-time trader you will be having lots of free time to spend your family and friends.
Another thing is that trading isnt something that requires readings too much books. Its not like investing where investors will have to be reading and books and a lot of them to keep up with whats happening, and also youre making your money daily and not going to wait for months or years to get your money back.
