Writing your seed phrase on paper and locking it in a drawer is an order of magnitude safer than storing it on your phone. A cold wallet keeps your private keys offline at all times. As long as you don't disclose them or connect the device to the internet, it's far more secure than a hot wallet. That's the standard setup for holding a large position.
With volatility like $SOL , the key to holding on is keeping the keys in your own hands, not handing them over to a platform. Market structure is one thing; position size is another. They're two separate matters.
Where do you keep your seed phrase? Let's chat in the comments.
