gonna throw out a nice generic statement.

any PoW chain that…

• had a fair launch
• is actively developed
• is algo dominant
• supports reasonably solid privacy
• is widely accepted as MoE/SoV

is a good option.

bonus points if it…

• is “light” on chain storage requirements
• has reasonable on-chain scaling possibilities
• has a quantum fail-safe

as for specific projects, LTC, BTC, XMR are all interesting because they hit various combinations of the above, with LTC being the most interesting to me.

I am looking for a fiat replacement, not an “investment”. I need that replacement to be simple, reliable and absolutely solid.
