Bitcoin is a cool cryptocurrency, which historically is deflationary and gains value overtime.
The dollar is inflationary and loses value over time.
All other currencies which are weaker then the dollar lose value overtime, but faster, so the dollar is the go to currency to hold value.
Stable coins are pegged to the dollar, and can be exchanged for dollars anytime, so they are a convenient way of holding your dollar wealth and moving it around.
Bitcoin is touted as a store of value and certainly overtime it has gained more then any other asset in history.
But Bitcoin is cyclical and losses occur
I suggest you hold a small amount of Bitcoin, but consuder using stablecoins to lock in your profits during a bull market or cry all the way home during the bear market.
