I hope this will never happen of course, but for who have invested capitals, it may be a question someone have answered accurately to avoid an important loss.
There is no need to worry too much about Bitcoin's journey because you can check it on historical data and even though Bitcoin has experienced a fairly sharp decline in its journey in the market, there is always momentum for Bitcoin to rise again so that its price in the next cycle will increase. Excessive worry actually occurs because someone does not understand Bitcoin's journey so they feel panicked and worried when Bitcoin experiences a fairly sharp decline.
Forget about the decline and increase your investment responsibly so that you will see new price movements in each cycle that runs and most importantly do not panic so that it will be much easier for you to understand the journey process.
Panicking are mostly associated to those who approaches Bitcoin investment in terms of seeing it as a quick and get rich scheme for short term profit maximization within the shortest time frame, anyone thinking about Bitcoin investment should have long term perspective hence there wouldn't be any need for panicking because you are not yet ready to sell but to keep increasing and holding and that's is the best approach because it values can appreciate over time resulting compounded value of the assets over the long term. However, anyone investing from his or her discretionary income is not meant to panic because it is assumed that the basic needs are already taken care of.
My simple advise is that if we do pay attention to how and when Bitcoin will DIP then we won't be able to invest enough into our portfolio. Those who aren't scared are the ones taking charge and purchasing quite some numbers of Bitcoin without being disturbed about any probability or declining factor.
Bitcoin isn't risky, sometimes we bring the risk to our investment like for those who would invest with capital that is not meant for investment purpose, doing such can hinder the long term approach and when raise the urgency of that funds then the investor will be forced to withdraw whatever it is without considering the fall in price, all he want is to acquire part of the investment in other to meet up with returning the money. Practices like this leading to panic isn't a likable approach when dealing with Bitcoin investment.
