My two biggest concerns. If not for those two I would already go all-in into bitcoin.
  1. We trust that satoshi-era coins are truly lost (and won't be dumped on the market). It's a trust, because we can never be sure.
  2. Not having quantum resistant UTXOs, when they are needed.
the quantum issue would be a problem for many aspects of today's world, not just bitcoin..
