No, Its too simple because We are progressive in technology but a physical trade means be always physical. Crypto is next generation of economy but we can't forget about it that crypto can be devalued in a sec but on other hand we cant remove physical assets like gold which more safe and stable in its Capital. For example if we have to go through any crisis in which we cant survive with technology then there is no digital word existence.

So Simple mean is may be for sometime Crypto(about impossible) can cross over the Gold capital but it can't survive for long.
