Market sentiment is changing and Bitcoin is always associated with volatility, so it is difficult to say in this process that only holding it for the long term will yield profits or maybe it's not even possible to say depending on how much Bitcoin you've accumulated and how long you've held it. Holding for the long term is definitely a broad-mindedness for investing but if you have enough Bitcoin and are aware of the market situation there may be a chance to make a profit, because of the rapid rise and fall of the market even if you have a portfolio full of Bitcoin no distinguished investor can guarantee a profit.
Try not to be confused about Bitcoin, you are a senior member, I expected you to know better that the way Bitcoin is wired, it is more beneficial to hold a little bit longer because since Bitcoin is an asset that appreciate in value overtime even common sense will make us understand that as time passes by, it value is going to increase and you that is holding it, is going to make more money.
You might argue that some folks buys and sells very quick after making a few box from it, that it's still profit, but guy take note that selling for minimal gains can't have any significant impact on your finances status, so that is why it's advisable to hold for an extended period of time like 10 to 20 years in other to milk the best possible revenue from your Bitcoin holdings.
