Honestly Bitcoin is far too volatile to keep its value. You can hold onto it for years and watch it increase in price, but if Bitcoin ever falls again, that worth also plummets. Bitcoin has already dropped considerably over the years. Before the pandemic if i remember correctly, Bitcoin was reaching near $60,000 in worth. But now, it's a little under $30,000.
It dropped down to $15,000 at one point, so the store of value as you say, probably doesn't work so well with bitcoin, as it's unpredictable and could lose its worth at any moment.
