The Binance hack was another hard blow for all of us. In a universe that lives in constant vigilance and apprehension, with many highs and lows (and I think more lows than highs), every precaution is necessary, and when something happens that is not even within our control, we become even more upset.
I don't leave anything on exchanges anymore. It's been a long time since I stopped, precisely to avoid this kind of thing. I only use exchanges to transfer tokens at that moment; I log in, do what needs to be done, and leave, just like that. This doesn't make me immune; something bad can happen to our money anywhere, and unfortunately, nothing is 100% safe.
Even money under the mattress isn't safe, so the secret is always to diversify everything, leaving a little here, a little there, dividing to conquer or dividing to protect. But I reiterate that nothing is safe in this life. Even with all the care, anything can happen, whether we can control it or not. Therefore, taking risks is something we should try to avoid as much as possible.
I believe the best rule is this: diversify, always keep your portfolio in several places, as different as possible. That way, if you unfortunately lose something, you don't lose everything at once, only a part. This is our daily life; in such uncertain times, trying to protect ourselves in any way possible is what we can do.
And you? What do they usually do? What do you do to avoid crypto exchanges?
