Whether you believe Bitcoin is worth owning I definitely think that it should be at least a small part of your overall partfolion as a speculative asset.
When bear market comes, you will see the reason that bitcoin is better when most coins and tokens do not get to all-time-high during bullrun. In the bear market, you will see altcoins that will fall more than 10 to 25 times. If you want to see some of them, I can give you names. Gamble with altcoins but hold bitcoin.
