It is a project, right? so it my go down, shut down, etc... so the only way to keep you ur coins safe is just transfer them to your Hardware wallet. In my opinion there are some safe places to store:
Exodus PC/MAC wallet, Ledger Nano S wallet, Trezor wallet, or I usually go to coin's website and download the wallet to my PC/MAC and keep my coins on my PC/MAC. Good exsample is Davor coin or Bitconnect. Projects are gone, never be the same as it was, but actual coins have blockchain so they will always be, and you can keep them on your wallet on your PC/MAC :) Thanks :)
