Indeed.
Almost everyone knows about Bitcoin's volatility, although while we all anticipate price fluctuations, it's impossible to predict the particular direction and magnitude it'll take.
You're also right that even people who believe in Bitcoin's long-term potential for growth, it's also impossible to predict the exact timing, the extent it'll grow and the exact pace at which it will.
These uncertainty shouldn't actually be a bad thing, to me, it's exactly what makes bitcoin investment exciting and adventurous because the more you advance, the more you learn and discover new techniques and approaches, learn from your earlier errors and advance.
It's very crucial for an investor to know exactly how to understand and manage these uncertainties through risk assessments, long-term perspective, regularly balancing one's portfolio, diversification and always eager to research and learn more.
Bitcoin is bound by uncertainty of what the price would be especially in the future. But doing one interesting thing is that you can be uncertain what the price would be tomorrow next week or next month. One thing is assured that the price in the next 2 to 3 years would be greater that what it is today, So the question is two to 4 years a so big that investors won't have patience to wait? Many persons are misled by the dip action currently thinking it will dip even more. My dear one doesn't need to be persuaded much a true investor will see an opportunity like this and buy the dip instead of thinking about where the price would be soon.
There's isn't any guarantees that one is going to make more profits in the next 3 or 4 years and above, because we can't actually tell the or predict the market movement. But still is better to have some good quantities of bitcoin stash, than having none just as sir JayJuanGee said inorder to be prepare for the up one should prepare for the down also by accumulating. The reason most time I usually encourage long-term holding, is because whenever one is holding and accummulating for longer-term purposes he or she will have enough time to stash some good quantities of bitcoin in Their portfolio, and the other reason is that base on history bitcoin as being tend to be increasing in value the past years , so we all believe such may continue.
