Bitcoin is not a store of value, and anyone that confuses it for such will suffer dramatically.
Short-term, yes they might suffer. If you bought at $60k, your portfolio doesn't look that good right now. But why are you thinking short-term? It's been proven time and time again that its value increases over several years.
And don't forget that when bitcoin falls by 10%, alts fall by 20%. When bitcoin falls by 50%, alts fall by 80% or 90% and some never recover. Bitcoin has recovered every time and reached new highs.
And as far as I know, based on 'store of value', it should be for long term and not just for a month or 30 days. So still, it falls under the definition if you are going to hold for years, just like the majority here.
In any case, Charles Hoskinson take is not new to us, so what else is expected, not just from him but from the rest of those who are going to criticised bitcoin. And it seems that there argument sounded like a broken record already.
