Centralized mining, centralized development, price based on artificial scarcity of coin count, fee system that doesn't work without artificial scarcity of block size. The whole thing is honestly a complete joke compared to metals.
"Centralized mining": competition will rise, see Russia announcing to enter in mining and chip production.
"artificial scarcity": money has to be scarce to have value. artificial money calls for artificial scarcity.
"fee system": see above, but I have my reservation about the BTC fee system: full blocks and large mempool means that fees are underpriced.
"Promoting that everyone on earth use the same artificially scaling constrained coin": who is that BTC maximalist? let many coins blossom and the market will choose.
"a huge step backwards from gold and silver": You can't strike gold by holding gold. Crypto is for speculation and other advantages. Gold is just to sleep well.
