I think speculation plays an important role in trading because if a trader picks the right trade and speculates accurately then its very likely to have high returns. When we say high returns it also means that high risk, so strongly advise to those who are interested in trading, one needs to study first how trading works and do a lot of research to fully understand the system. Trading is not a joke that you can just easily trade without speculating correctly because it could mean a waste of time, effort and also resources. Ive tried trading in the past and I just use instinct instead of speculating properly and it cost me a lot of fortune. Therefore, trading needs proper speculation to have high chances of high returns.
