To me, planning to accumulate bitcoin in order to sell it all seems like trading rather than investing, but they there might be nothing wrong with coming to bitcoin with g it all down the road, yet if we spend time accumulating bitcoin and studying bitcoin, we may well come to realize that selling our bitcoin is not really any kind of a great plan... yet each of us has to figure out how to deal with our bitcoin once we get to a position that we might be consider to have enough BTC or more than enough BTC.
Accumulating bitcoin and selling it all off doesn't really make sense at all. Even if an investor has accumulated as much bitcoin in such a way that his bitcoin investment can be able to sustain him that he does not needs to bother himself with work, it will be very wrong for an investor to sell off all his bitcoin and become a no coiner unless if the investor has few days or week to live. So instead selling off all our bitcoin and become a no coiner, which is also more like trading, it will be best to withdraw from the yielded interest once we have accumulated more than enough bitcoin instead of selling all our coin.
Regardless of how big the person Bitcoin stash is, selling it off at this present rate is too much of a loss to me because we are still in the early days of Bitcoin, and $100k is nowhere near it peak price, so for an individual to sell now, it's either he is a trader or he has just few days to live just as you have already said, because no true Bitcoineer will sell too early and will be ok being a no coiner, without waiting for years and milking the best possible dividend from his Bitcoin investment, it's unheard of, unless that person doesn't really knows the potential Bitcoin has, because anyone that knows it value and potential wouldn't act in such a manner.
In fact, those who decide to sell at the current price are going to lose the opportunity to make a lot of profit in the future. Because the current correction is going to end very soon. And Bitcoin will pump again, but those who sell their holdings now will lose this opportunity and then only regret it.
Those who are real Bitcoin investors know very well that the price of Bitcoin will go much higher in the future. And they never get scared of such corrections, rather they buy more Bitcoin at this time.
Moreover, real Bitcoin investors never think about the price of Bitcoin, they just continue holding continuously. And as long as they decide to continue holding (10-12 years/3 cycles), they only hold accordingly and never think about the price. And they are the ones who get the highest profit in the end.
