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.
If you generalize super rich, you will end up with a misunderstanding.
Not every super rich got their wealth in the same way, some go through a long struggle to succeed. So, it is untrue if you assume all super rich got their wealth without hard labor. Even Elon Musk has an obstacle to promoting electric cars around the world. So, he is surely struggling to deal with the obstacles. But super rich never stops struggling, they continue their efforts till they succeed. They have a strong mentality, never give up, and think ahead. That's the difference exactly!!
The solution is transferring their wealth into digital asset.
The solution can be varied, not only converting the wealth to digital assets. Land, gold, and real estates are also the right solutions.
