You were making sense dude in your post but you were kinda deviating from the point there by contradicting the whole point. When you say a negative situation can cause someone to face a lot of losses where they can lose their holdings without been specific makes you look or sound like a trader. The only time someone can lose their holdings is if they are trading or they didn't prepare before venturing into Bitcoin investment because there is a high chance of incurring loss if you don't prepare before entering into Bitcoin investment because you will definitely sell off your investing when you have little or no emergency and reserve funds.
Price volatility only causes investors to gain an increase or decrease in the value of their investment, while the amount of assets remains the same. This is no different from spot trading, but very different when done in futures trading. Spot trading does not make you lose assets due to price declines, while you will lose all your assets and money if your position is closed due to price declines in future trading.
If you are a trader, buying dip and dca can also be done as a strategy. If the price goes down, you can accumulate and that makes the average purchase price lower than before. It is the same in investing, only the time frame is different. Investment is expected for medium to long term goals, while trading is for short term goals.
