I've heard that in some situations,

others will ask you to open a trading account on the spot,
check balances, transfer records, and transaction history.
Exchanges provide convenience and liquidity,
but assets essentially belong to a custodial state,
and to make assets more private,
you need to trust the platform, rules, and the stability of the external environment.

The core value of cold wallets lies in:
- Self-held private keys
- Assets not relying on any third party
- Transparent rules that cannot be arbitrarily changed

In other words,
a cold wallet is like your own safe,
with the key only you have,
"Not your keys, not your coins."

The construction of the cold wallet ecosystem is also developing rapidly.
#OneKey team is expanding and has opened multiple job positions.

I also gifted many friends in need with @OneKeyHQ
cold wallets, which are very easy to use.

Using exchanges for trading and cold wallets for long-term storage is a standard operation for many veteran players in the crypto world.
