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.
If you been in bitcoin since your forum registration date of August 2016, then surely it is possible that you have accumulated enough BTC, yet to me, you sound like you are looking at bitcoin like a trader, and you are ultimately likely to be ending up selling too many BTC too soon, because you do not recognize and appreciate that long term investing and building wealth takes time, and when you get there, you are likely able to recognize an ability to start to make withdrawals... but yeah, if you are fucking around and trying to figure out when to sell in order to buy back cheaper, then you are playing a different game, and you are likely going to have fun staying poor because you are selling too many BTC too soon instead of having a plan that ultimately results in being able to either engage in
sustainable withdrawal practices or
raking practices. Raking practices can usually be started quite a bit before sustainable withdrawal practices, but guys can come to differing conclusions in regards to employing such practices.
Indeed he sounded like an investor whose intentions are for trading because I see no connection between long term holding and the possible way of taking profit, though I may not know his own definition of holding but in terms of his statement above he is obviously mistaken holding for trading, however your explanation to him is very clear and understandable so the early he takes another turn on his Bitcoin method of investment the better for him because it is believed that so many investors have shattered their investment do to a possible way they feel they can navigate into getting a quicker profits.
