If you intend to hold Bitcoin, you will be ready to increase your investment at any time. Because your holdings will depend on when you should invest. Whenever you invest for long term you can participate in your investment at any time by following DCA method. But whenever you hold for a short period of time you have to buy bitcoins from the deep market. And when the right time comes you have to sell this hold to reap the profit. But I would suggest you to definitely participate in long term holdings the benefits will be more if very less.
Having a Bitcoin investment will certainly be able to prepare for a better future because we can see very good developments at the moment. Every Bitcoin we collect will be able to benefit if we understand well how to collect it, if we use the DCA method in collecting Bitcoin of course we will hold for a long period of time to get profits from the investments we make and we can collect according to the plan we have set and do it consistently. Of course this will be able to prepare for a better future and it will indeed be better for us to hold Bitcoin in the long term to achieve the targets we invest in.
