To build a good Bitcoin portfolio, in addition to buying regularly, it may be a good idea to buy a little more aggressively when the market is in dip.
In my opinion a good investment portfolio requires longer time and it is necessary to purchase Bitcoin regularly. Moreover building an investment portfolio requires a lot of patience, time and need to keep themselves steady during the market updown. As you mentioned that buying a little more aggressively when the market is a dip, it is okay but buying it aggressively may have to be considered on your financial ability.
Because the amount of money we budget for our regular Bitcoin purchases comes primarily from our disposable income, that is, from the money in our budget set aside for investments. So I think it might not be wise to aggressively invest all of your hard-earned money, as a result regular Bitcoin purchases may be temporarily halted.
To build a portfolio, you do need patience so that you don't make mistakes or rush into making decisions other than routine purchases. And if your goal is long-term, this is something you should always remember and must be planned and directed well.
I mean because the goal is long-term, planning must be done when you want to make aggressive purchases that you should have planned or prepared well in advance outside of important needs such as money, reserve funds, and routine purchases that you have set aside outside of those needs so that you can make aggressive purchases when the market is down without having to change or sacrifice other important money or money that you have arranged as well as possible just for aggressive purchases and that will only mess up your plan or deviate from what you have arranged well.
And I repeat and remind you that your goal is long-term which means you have plenty of time to build a portfolio well and get to know the market or Bitcoin movement well so that you can do it very well with very thorough preparation so that everything goes well to generate extraordinary profits in the future.
