2x return monthly? See possibility is always there but realistically speaking, the chances are low.
Of course one might end up buying some random asset and it rises such that the trader sells it to realize a 2x profit. But at what cost?
The market does not determine who is going to make money today or in 30days. It is not like a mill churning out flour every day. It is a speculative market and one needs to the seize the correct time and price at both buying and selling.
Simply put, profitability is never guaranteed in trading. Yes, it can be profitable at some point but how often? This is the reason why trading can be link into gambling since the chances to lose is high while leaving the rate of winning very low.
If you aim to double your returns within a month, get more side hustles and gain multiple income. Maybe that way, your ideal returns will be met. Trading is good, but it's hard to expect returns at all times.
