Similar to your 401K balance or your stock portfolio or your bank balance?
Do you think your bank has a vault filled with all of the money you have deposited?
It's all 1's and 0's
The question is:

OR
The 1's and 0's in your blockchain secured wallet being devalued due to market volatility.
One is just slower than the other................
