Very little, if at all, the value of crypto has been created independent of the money supply. According to economists all inflation is created when the money supply increases faster than the output of goods. You can think of each crypto as its own startup where the value is locked in the startup and only a little bit is converted into currency but the money supply does not change since there are no new dollars being created. The dollars to buy it have to come from the current money supply.
Also, unlike other assets, such as real estate, few banks are willing to make loans against it so the money supply has not expanded much that way. So even if crypto goes to $0 it won't affect the money supply much.
If crypto becomes an actual currency that can be directly exchanged for goods or banks will lend against it without much trouble then maybe it will affect inflation since at that point 2 currencies would be competing for the same goods.
