Yes we have to plan long term in every field, we can't earn anything with fast and easy way, for that we must have proper planning, patience and dependability. Proper strategy and long-term planning are crucial, especially when it comes to Bitcoin. If an investor considers Bitcoin as a get-rich-quick scheme, he will be at a loss later on, as Bitcoin always provides long-term returns. We first need to build a strong income base which will pay us money regularly and then a investor continue to invest through the DCA method and gradually build Bitcoin Stash. And of course Bitcoin will continue to "Hodley" for the next two to three cycles, then that investor can make a profit from it.
To make an investment successful we need to keep a few things in mind.
1. Dependable/alternative source of income.
2. Long term planning and determination in investment.
3. Ensuring portfolio security.
4. Keeping funds ready as per requirement.
These points should be given importance to make an investment successful (there may be some more points). I find DCA as a convenient and easy strategy for investing. I see very little chance of loss here if you are a long term and proper planner. If you are planning to get rich quick from Bitcoin then you are almost guaranteed to be disappointed with Bitcoin. Because Bitcoin is a profitable long-term investment, you need to wait for several cycles (1 cycle=4 years approx) to get profit from Bitcoin.
