Monero is less scalable [than Bitcoin] because you have to store all transaction outputs (key images) instead of just unspent transaction outputs, since Monero does not know which outputs are fully spent (for larger ring sizes). And these must all be stored in fast random access memory for double-spend prevention. That’s an ever-growing pile of data!

While in Bitcoin, you can offload older UXTOs to a slower memory, because the access pattern is “UXTOs die young.” Also, UXTO set grows much slower or even can be stable (“1 UXTO per person”) while transaction volume grows forever.

Bitcoin scales way better than Monero or Zcash (that has the same requirement to store all “nullifiers” to prevent double spending).

[T]he one and only litmus test [for whether a blockchain is truly decentralized] is whether you can fully control your money in the presence of many other people trying to control your money. Bitcoin is the only one that passes, by a large margin.
