One question bothers me a long time and I am not sure if there is anyone that thinks about this before. Let's say you invested $10K in Bitcoin when the price was $20K, and some time later the price pumped to $40K, which means the initial capital is now worth $20K. For some reason, you need cash urgently so you decide to sell the Bitcoin you own for cash. You do it and now you have that $20K on hand.
In this process of trading, your profit is $10K for sure, regardless of whether the Bitcoin price will pump or dump. If you won't invest again, this beautiful success should be what you are proud of. However, 99% of us will choose to buy again and hope for the next success. However, now you buy at $40K and the price may drop to a new low below $20K later, and the profit you gained from last trading may be eaten up gradually by the market dump.
Connect the two dots(two extreme conditions) and draw a curve, high chances are that at last, your profits from all investments may not be that much, at least much less than what you expected when you first gained that $10K. Therefore, all the occasional profits between investments may become fixed or variable costs that these investment must pay.
Does this sound logical to you ? What do you think of all the interval losses from the investment gains ? Please let me know.
That's the gambling side of investments, it accompanies all the investments. Some people actually love the gambling aspect of investing, while others prefer getting stable but not so hig income. And there is one more thing with income after withdrawing money: the value of usd also can be different at the time of investing and at the time of withdrawing, so winning a gamble in dollars doesn't always mean winning it in true values. Especially if withdrawal is around 110-120% of the initial sum, it is often a problem. The main values are within personal psychology and priorities, not in the numbers...
