I get what you mean. The buy-and-hold strategy is especially valid for Bitcoin and has been a proven way to make gains for years. But Bitcoin has different uses. It's not just an investment tool. I've been buying and selling things with Bitcoin for 12 years. For me, Bitcoin is money.
Some people see it like a stock, some see it like gold. But as it was originally intended, Bitcoin is a means of exchange that can stand strong against inflation. If you clearly separate the coins you keep for investment from the ones you use in daily transactions, you'll be more successful.
I totally understand your point mate, infact the point you made, I mean your preferred use case for Bitcoin is the reason why Satoshi created it, a means of carrying out transactions that's more secured and don't involve any third party but lately, Bitcoin has evolved beyond that and now mostly seen as a stored of value that's why you see some whales all over the media advising folks to hodl it instead of selling, as you can see the numbers keep increasing overtime, what the price was 4 years ago is not same or close to what it is currently there's a big gap, which shows that if one can built a portfolio for 12 years and hodl for that long without selling, there's lots of profits to be made but the big questions is if people can be that patient.
