Hi,
I lost some coins this year (my own fault in Phising)
But if you send your coins to multiple wallets you can split your investments better.When your wallet is hacked you only lose this wallet.
This is my lesson for the next time

(and some other securities)
What do you do to secure your coins / tokens?
This is actually a nice input that I think its reasonable enough to be considered. However, above this, it's important to watch carefully our involvement of wallets in any airdrops, project or activities that can open the door widely to phishing, hacking ..etc.
