I think we need both luck and skills.
why?
You know trading is the best way of earning big amount of bitcoin.But a newbie or anyone who don't know about trading can't become succeed on it.So, every trader needs to have proper skills too become successful.And as like gambling trading also depends on luck but not much.Skills are also very important, so we need both.
Even if they have both luck and skill doesn't mean they can't lose. They still can lose but the different between newbie and experience trader is consistency for achieving prefereed profit ! If they stop, they already accept the fate but if they keep continue trading , they can success as millionaire
Trading is regarded as a form of gambling which has risks of loses but a combination of both luck and skill will bring more success and profit when we get to be more experienced.
The fact that trading also involves the possibility of losing doesn't make it one and same with gambling though that's often the view of those who have never gone into trading proper. In trading movements in price is determined by market forces and a trader that understands those forces can accurately predict the market most of the time, unlike with gambling, the player is at a lose what is coming and often times, it is the house that decides their fate. Moreover loses in trading can always be managed and limited at any point in time. A loss in gambling is almost always final and a player is left to watch helpless as their money grow wings right before their eyes.
However there are some traders that can be said to be gamblers. Those are the ones without any skill or strategy and incidentally, they usually get what was coming their way. What's funny is that those are the ones that turns around to say trading is one and same with gambling, which relies 99% on luck.
