There are powerful financial interests who want and desperately need to "prove" that bitcoin and gold should not be considered safe havens.

These financial interests are willing to spend an inordinate amount of fiat money on discrediting alternatives to the fiat banking system.

For example, these financial interests accumulate lots of borrowed and paper gold and then dump massive amounts of fake gold during a stock-market downturn to depress the gold price exactly at that point in time.

They also do that with bitcoin. Centralized exchanges are more than happy to lend out their users' bitcoins for a fee to financial manipulators. Therefore, as long a the market capitalization of fiat values is relatively large compared to bitcoin and gold, it will be possible for financial fiat interests to "prove" that bitcoin and gold are not safe havens. In fact, given the fact that the total market cap of bitcoin is still much smaller than the one for gold, it is even easier to manipulate the bitcoin price than the gold price.

Bitcoin still survives in spite of all these financial assaults.

Therefore, the flight into alternatives will be exponentially slow at the beginning. It will take a prolonged depression in fiat values along with long, robust performance of bitcoin before the flight into bitcoin will be able to commence in all earnest.
