Buy on dips should not always be the case, why not concentrate in buying when you are ready, must it be on dips, people should know that bitcoin is an asset no matter how dip it goes, it has never stop giving people hope of shifting to positive position, I think everytime is an opportunity in bitcoin that's why continues accumulation is the best irrespective of the price any day any time.
It's really important for beginners to fully understand bitcoin before they start investing in it. They should know what they want to achieve and the strategies that go along with the type of investment they want to make. Also, it's important to know that bitcoin is not something you can make quick money from so it's better to have realistic expectations.
I agree that it's not always best to only buy bitcoin when the price is low. Instead it's important to be financially ready to buy whenever you can no matter what the market is doing.
