- Unlike Bitcoin, Monero's monetary issuance is not auditable, which could prove a major problem in case of an attack, potentially leading to inflation.
- Monero faces blockchain bloat issues due to its ring signatures. It cannot scale gracefully.
- Privacy and transaction cost concerns with Bitcoin have largely been addressed by Lightning and potentially other upcoming layer 2 solutions. A lot of work is being done here. If you are technologically inclined, you can also participate: https://lists.linuxfoundation.org/pipermail/lightning-dev/20...
- KYC happens on exchanges. Buy your BTC on decentralized platforms like Bisq or RoboSats and be done with KYC.
- A private-only ledger can pose challenges when transaction notarization is necessary. Bitcoin lets you choose between a private L2 transaction or a public blockchain transaction.
That said, I love Monero and am glad it exists.
