Money is simply a store of value that can be used to exchange value.
Banks are a centralised location that can store money on behalf of clients.
Crypto is a string of 1's & 0's that can represent money or many other things.
Historically money was kept by the user, and banks were a later addition to the monetary system.
Therefore with the advent of crypto we have gone full circle.
Users are currently storing their own 'value' perhaps insecurely given the loss of a mobile or a virus can wipe out that value in the same way a bag of gold or silver coins could be stolen or lost.
For crypto to become mainstream a secure way to store their value needs to be found, and needs to be easy to use
Do we want to go back to centralised storage? or is there a way a user/owner of 'value' ie money can secure it, whilst at the same time not be subject to a centralist model?
