Honestly, Trading has nothing to do with luck, is ether you are experienced or you are ready to continuously losing funds.
We can't deny that sometimes luck may have a role in trading, too. If we aren't lucky, the market trend can change suddenly and we lose the chance to get profits. But we don't rely on the luck because the chance to success will be small in this way. If we rely on the luck, we mostly lose money because we have no proper way in trading.
Trading requires experience and this knowledge must be acquired to make good profit wether you are trading on Spot, future or margin options.
Indeed. Knowledge and experience are very needed, these are the basic things in trading. It is true, any kind of trading (spot, future, margin) requires knowledge and experience. These are the factors to determine the success of our trading.
I think that those who Hold some coins for some time ( that is, long term) could be regarded as the lucky investors.
I don't think so. Both traders and investors are the same, we all need to have proper knowledge and experience. We don't rely on the luck, it is not gambling. We only can rely on the luck in gambling, but it won't work in investment and trading. So, there is no term of luck investors or luck traders.
