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.
Many investors or holders lost their patience and had losses because they sold their bitcoin before the rally in late of 2020. If they had hold their bitcoin from late 2017 to late 2020, they would have not gotten any loss. They got losses because they don't have enough patience or only have short-sighted, short term investment view.
Their losses are made up of their impatience, bad entries, severity of market, short-sight.
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.
More criticism appears in bear market than in bull market.
