The super rich are so much worried about the revolutionary financial technology Bitcoin and the Blockchain. They need complete understanding to not to fear of the future. First, they did not earn their riches by hard labour, second they must know that they will never use their mountain height of wealth in one life time.
Well I guess they did work their ass off early, getting enough knowledge on how to become rich by investing in any instrument, like stocks, mutuals and other financial assets. So there is some form of hard labour there. And probably this will be the same with crypto and bitcoin, this rich people will need to learn the technology.
Their wealth will be inherited by their children, they must teach their children to make money and enjoy their own labour and they must setup charities to help the humanity.
Hopefully their children will learn how to protect their wealth and asset and be the next generation, and yeah, they will learn how to help humanity with that enormous money.
The solution is transferring their wealth into digital asset.
Partly, but I think they are old and traditional, so they might as well stick with what they know of, and that is stocks and others. And maybe their next generation will start to move it to digital assets and they are more adapt to cryptocurrencies.
