Account protection based on systemic or nonsystemic risks? I'll try to answer both.

We are an ERC-20 CRYPTO employing zsnarks, keypairs and cold storage of private keys just like ZCash, Golem, Gnosis or other ETH token. So you can rest assured we dont hold your private keys and you can store them in your Trezor or Ledger Nano if you want the securest protection out there for your wallet account.
As far as systemic security, we ride on the ETH platform and monitor and lobby the ETH foundation on security frontiers. We expect that after the metropolis fork we should be able not only to enable safe refunds on wrong sendoffs but also eliminate the existing threat of quantum hacking with masking enabled.
Look at it this way,  if you hold fiat thanks to inflation you are guaranteed to lose at least 2% even in the strongest currency annually. In 10 years your "savings" will be 30% their value and in 20 will be half!
