Bitcoin has shown to be a fantastic value store in 2020.
If you consider the whole year, then yes. But short-term, there was a 50% price crash when the pandemic reached Europe and Bitcoin fell from $9/10k to under $5k.
Those who claim Bitcoin is simply a value store should accept that it is the only worldwide P2P payment system whose transactions cannot be banned.
It can't be entirely banned, but a government could make your life harder if you are involved in Bitcoin. China has successfully banned BTC mining. Banks can be instructed to reject all transactions that originate from crypto exchanges and businesses that deal with cryptocurrencies. But they can't ban you and me meeting for a coffee where I give you fiat and you give me bitcoin.
