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?
What I do in order to secure my coins is that, I secure myself, as simple as that. In order to become secure, you should be aware of the things hackers does on the internet. Also, using multiple wallets might cost you a lot of transaction fees.
