Yes, I agree. Activity and resource credits are the main feature. Although they're not that different.
In order to be valuable, there are basically two models.
1- Burns: similar to stock buybacks.
2- Resource credits: Similar to stock dividends.
Both return value to shareholders and without this all is speculation. This is true for every crypto.
The Spk network SIP is basically locked liquidity, which is a form of burning. Similarly, the Hive DAO is locked liquidity, which can only be released by governance voting. So when I say "burned", it's not technically correct, it's just locked in the DAO in the form of HBD.
Bitcoin as the best store of value and Eth as the best collateral are both speculations imo. People speculate that those assets will be bought and held for their better security. I have nothing against speculation, and hold both BTC and ETH as I agree, but in order to have intrinsic value, we need buybacks or dividends.
Eth has buybacks, Hive has dividends. Bitcoin has dividends in the form of fees as well, but only the miners can earn them, not every bitcoin holder. Time will tell if this is a flawed model or not.
There is, of course, the "network effect value". Some people believe that the more users there are, the more valuable a token, even if it doesn't capture value in the form of burns or dividends. I don't think that this can hold true in the long run.
Also important to add, Proof of Brain is a form of dividend and burn at the same time.
Hive power is locked liquidity (temporary burn), and it allows you to allocate inflation (upvotes are like a dividend).
Someone might argue that governance gives value without being a burn or a dividend. But I disagree, because if I own 51% of the governance token, I can decide to allocate myself a revenue stream in the form of inflation.
A more practical example would be uniswap governance choosing to earn from the exchange fees. It's always about burn or dividend.
