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?
I practice the same. I have more than 10 MEW wallets and a Ledger as well.
Ledger is for long term storage. MEW wallets are for quick fund and token transfers as I don't carry my Ledger always.
