To me both exchange storage and hardware wallets have their pros and cons. Exchanges offer convenience and access to features like instant trades, staking, and especially those seeking liquidity and quick trading access. However, they also comes with it own disadvantages with breaches but BingX handled it better with the recent event, The exchange promised that no users will face loss and they have been doing all the necessary things to fulfil those promises.
However, hardware wallets provide greater security, particularly against online threats, by keeping private keys offline. That said, they can be complex to set up and may not suit everyone.
It’s all about balancing security and convenience, Diversifying between both options and depending on personal convenience which might be the safest route to protect your BTC in the long run.
