The safest way to store cryptocurrency long term is in a self-custody wallet where you hold your own private keys.
The biggest mistake most crypto holders make is leaving their coins on an exchange. When you store crypto on an exchange, the exchange controls your private keys — not you. If they get hacked, freeze withdrawals, or shut down, your access depends entirely on them.
Oppi Wallet solves this with true self-custody:
— Your private keys are generated on your device only
— A seed phrase (12 to 24 words) gives you permanent recovery access
— No company can freeze, seize, or lose your funds
— Supports Bitcoin, Ethereum, USDT, Solana, and 40+ coins across multiple chains
Key storage best practices:
— Write your seed phrase on paper and store it offline
— Never store it digitally or take a screenshot
— Enable biometric login and two-factor authentication
Over $3 billion in exchange-held crypto was lost in 2025 through hacks and platform failures alone.
Store smart. Your crypto is only truly yours when you hold the keys.
