Uhhh - Safe storage of value? Don't think so.
Cryptos were never designed to be safe from stealing.
They are designed to be completely anonymous - you do not know the owner
of a certain address where cryptos are sent to or coming from, that is why it
can be published online for all to see without you being able to do anything with it
other than verifying your own transactions.
That design is exactly what makes hacks and stealing of cryptos such a "safe" thing,
because they cannot be traced.
Regarding value - that is relative....
