this is the general theme, bitcoin has more considerations than just privacy, while monero has it as their marketing and can focus on it at the expense of everything else

for one, syncing a monero node takes ages, and requires fast storage for the entire block chain instead of only a UTXO database, do people generally run their own monero node? if not and they're using some wallet provider, that's not great for privacy either

also yes things like potential DoS attacks might fly under the radar for a more obscure coin, but wouldn't for bitcoin
