Tell that to investors in Fitbit or Palantir (for example) before they sold off after having good "momentum". Crypto investors don't even understand crypto, but that doesn't mean anything, because you can be left holding a long term bag whether you understand the underlying asset or not.
If you actually understand "investing" you will understand that you can't beat the indexes and are doomed to failure by trying to use "momentum" to do anything other than lose money.
