I have been noticing one thing for a few days, that in addition to investing through the DCA method, many people continue to save money to buy aggressively during market declines. If a person instead of saving money takes a loan to buy aggressively during the decline, then I think it may be a good decision for him.
It is not a good practice to first save money before you invest same into Bitcoin, that method may not be effective on the long run reason being that you may spend the money on something that is not Bitcoin when you encounter slight emergency. Instead of this approach, why not invest the money through the DCA method you mentioned as the money enters?
For example, he will take a loan of ₦200,000 and he can repay that amount in weekly or monthly installments of ₦40,000. If he proceeds in this way, he will not have to face the problems like Person A.
You are to only invest in Bitcoin with your discretionary income which is the amount of money left after you have settled your basic needs. It is never advisable to borrow money to make investment because investment is not guaranteed to give profits. I know you will not be happy paying back loan with huge interest over Bitcoin you bought during the peak and it dumps. As you know, Bitcoin is a long term game, so borrowing will not allow you give enough time to the investment in order to realize profits.
