• Can gambling or crypto trading/crypto investment be considered as a skill?
Of course. A lot of traders/investors(the successful ones) do a lot of research.
How is trading or investing a skill? Skill is something, that you do frequently and master it in a level that you do that particular job in a professional manner, quickly and efficiently.
Well, I don't think anyone can call themselves a trader or a successful trader at that, without having committed themselves to a frequency of a series of trading event.
As such I consider trading a skill if it has been done more than once for at least 2years non stop, if a particular technic has been mastered and can be improvised upon when trading.
Luck only greets you with success, if she found you ready, prepared, equipped or whatever word there is to describe a state where something happens like magic or reflex.
