I have always believed that the crypto currency is based on the blockchain technology which relies on the principle of decentralization and it gives us the freedom to hold our wealth with us without relying on any third party out there. I have been using multiple wallets but when it comes to the holding, I prefer hardware wallet as well as paper wallet (along with backup precautions) to store my funds. I highly recommend offline storage for anyone willing to ensure high security but even in that case, the holder must maintain psychical security measures.
