You can never say whether you have succeeded or failed until your time limit is up.
Everything has a risk and the level of risk will be proportional to the potential profit that will be obtained so when someone has to trade so that assets increase from the trading profits they make, there is nothing wrong, regarding the risk I think it is quite worth it with the profits obtained because there is nothing profitable without risk and someone who does that must be ready for everything including being ready with the knowledge they have and having confidence in the trades they make.
The DCA method is indeed quite good for future investments, we will continue to add assets to the portfolio regardless of the price of Bitcoin at that time but it is only within the limits of our ability without being able to increase rapidly.
So for someone who has long-term investments with the DCA method or trades to add assets to the portfolio I think both are good, depending on the trading knowledge we have.
You can not be more careful when it comes to trading. Admitting a 50-50 chance for your asset just a tiny chance of making it quick. Is it better to loose your money out of impatience?? I can bet you that you wouldn't like that to be a risk taker. People go out of their ways to borrow and trade and most times end up loosing everything. This is what you can avoid by strictly following your DCA with your Discretionary income. All you need to do is get a stable source of income and handle your bitcoin as your retirement plan and not a gateway to quick wealth.
Every body has a limit to what they can do and setting up your holding time would also give you a distinct direction and target to what you can achieve. Bitcoin would always be way up as the world has come to realise it's important value.
