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 would just advise being careful when navigating links from email and from telegram/Twitter/btt. You will lose money, even if they are on different wallets - it will not save you i think. I try to keep on separate wallets those tokens that I consider promising. This is a long-term investment.
