You hold your wealth in crypto you manage to save your wealth If not then your years of hard work could go just waste so people who don't have crypto will be in serious trouble get cryptocurrency and debit card to spend your crypto instantly.
People learn hard way that crypto is safe heaven.
Bitcoin is the safe haven and not cryptocurrency, our wealth should be held in Bitcoin and not other cryptocurrency. Hodling other cryptocurrency is a risk too because they can crash or lose value with no hope of growing back to the old price but you can be certain that it'll not be happening with Bitcoin hence Bitcoin is the only safe haven cryptocurrency and not all cryptocurrency.
Bitcoin is highly volatile and can be dumped at any time, even losing more than 70%-80% if it enters a bear season and that stagnation lasts for years. What would you do if all your money was bitcoin and it lost more than 80% of its value? So I don't think and disagree that bitcoin is a safe haven.
I don't know if there is any difference in the concept of safe haven between us but basically: safe haven needs to ensure stability, not an asset that is highly volatile or frequently dumped.
Most of the claims about bitcoin as a safe haven come from bitcoin investors and it is not yet globally recognized like gold. So if we're being realistic: we need to admit that bitcoin is not yet a safe haven.
