People think that they don't understand it, but I think they do. Berkshire Hathaway entire business model is buying cash-flow positive companies where the owners took on debt in the wrong time of the credit cycle. Their cash-flow can't service the debt, so they become distressed and "value". Berkshire Hathaway then swoops on with debt leveraged on their other assets and buy them.
A currency, like Bitcoin, where there are no credit cycles and debt is a lot harder to get is destructive to everything Berkshire Hathaway does.
