PIECOIN Wallet

[BigBelt55]

Can PIE be stored on Trezor?  Where is the best place to store Factom and NEO?

You can their own wallets and gain from Hodlin if that's your intention.

For Pie http://www.piecoin.info/ you can download their wallet there and stake.
Factom https://docs.factom.com/#introduction
Neo, use NEON, and you'll get gas which is like 20 bucks right now when staking, it takes a while to get any real amounts but since I'm hodling for what I plan to be years it works.

Be sure to keep them in sync with their respective networks
