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?
Such strategy may damage the mobility of your tokens. When coin is dropping down, you may want to sell it as fast as possible and multiple wallets are an obstacle.
