Let a trading position opens for 90 days is very bad in my opinion.
In this volatile market, one of most important principle is don't let your trading position opens like forever and only wait to get profit from it. You must identify when you have to close your position, before you open it. If you are trading with leverage, this principle is more important as it can help you to exit the market and proactively avoid liquidations.
Hmm, Yup for sure it's bad, and it's like you are sitting on an active bomb because it's not a traditional market where traders enjoy the certainty, in the crypto market even a long-time frame trader also uses the the max weekly frame.
Copy trading is not for newbies, even though by definition it looks like it is designed for those who have little knowledge about trading as they can follow the expert traders to execute trades efficiently but its completely opposite, those expert traders control your assets and take higher risks while trading and as most of the trades don't have enough capital as the expert traders do they lose most of their valuable assets.
Watch, analyze learn how those traders are trading and compare your own skills with and decisions with them then check out the results and compare your analysis-based results with those traders, this is what I recommend to newbies and those who like copy trading as it the only positive factor because you can improve your skills and trade decision making efficiency but never follow a trader and let them trade with your assets.
