If you plan to invest in Bitcoin, you must learn to control yourself. You must have the willpower to hold it for a long time. You must accept that there will be volatility in the market so you must not get discouraged but hold on patiently.
Between your dream and reality, what you want and what you will actually face with in reality, will be very different. Nobody spends money to buy something, for example purchasing bitcoin, and don't want to get profit from this action. In other words, no one wants to get loss from investment or trading but as said, there is big difference between your dream and reality.
You only can hold your bitcoin if you manage your capital very well and don't suddenly have need to sale your bitcoin. If you don't manage capital well, you will have to sell your bitcoin when you don't want and at that time, price will be lower than your target price. If you still have profit, just smaller, it's still good but if you have loss, it's bad.
Since you don't have much experience with Bitcoin, you need to plan in a way that protects you from losses, so you can buy Bitcoin using DCA when the Bitcoin market goes deep.
DCA bitcoin is a good strategy in long term and it helps investors to avoid risk, pressure to time the market, find bottom price but this strategy only can help investors if they have good capital management first. Use 100% money to purchase bitcoin, even with DCA strategy, and after DCA an investor has empty bank account, empty hands in cash, it will come to time of selling bitcoin at loss when something urgently happens.
