Instead of holding forever you could sell earlier. Buying coins with the intent on it going up to make money can be done with 'good' or 'shit' coins. If you have ever purchased penny stocks it's similiar in terms of risk/reward. Buying coins with a larger capitalization reduces risk/rewards.

If you believe everything is a 'shitcoin' and you want to hold them forever then on your death bed you can look at the value and determine if it really was a shitcoin or if the media made me think everything was a shitcoin.
