Wether they take quick profits or not Bitcoin still remains, it's all by choice and how we view from our perspective, each investor knows what's suitable and good for him because the needed funds used to invest was raised by him, despite all these happening, we only just advise investors to purchase/ keep on purchasing Bitcoin, restrain from selling and continue to hold for the long run in order to maximize the profits and store this wealth for a longer time.
Emergency funds are compulsory units in the process of accumulating Bitcoin that should not be neglected, life is full of unforseen circumstances that may come either at the appropriate time when funds is surplus or not, during this point in time a persons emergency funds will step in to resolve that issue instead of altering one's investment portfolio just to solve the need.
But unfortunately, not many Bitcoin investors can determine when they will take their profits. Many of them cannot wait patiently for the price of Bitcoin to increase very high. Most of them are still consumed by the issues raised by unclear news.
They will panic and make decisions without thinking twice. They cannot find more information about the situation that is happening so that they make instant decisions. For those who can still be patient, they can see when they can sell their Bitcoin and take the profit.
I don't have a problem when people who have gotten to their maturity date in bitcoin investment decide to sell part of their bitcoin, provided they are not going to sell off everything and have no bitcoin in their possession. But selling off your bitcoin possession due to panic and uncertainties is really a bad thing and there is no profitability in that. Know it fully well that there are those who specializes in spreading fud so that market will go down paving the way for institutional buyers to come in and buy bitcoin cheaply.
