It's very important that we don't keep all our coins on exchanges. Have them in your wallet and staking.
After MP incident, i have no coins on exchanges anymore as there is no need for it. PoS coins are so fast that it is easy to transfer when needed.
Earlier I used to stake my cold storage only once a week, but after seeing the attack on PoS/Vericoin, I rather have all my coins staking 24/7.
Also with PoS 2.0 you won't be able to "save up" on stake, so better to get used to staking 24/7
