I have less than 10 in localbitcoins and about 5 each on BTCC and their justpay wallet.
I don't trade actively, just buying around 1 coin every week or two since a few months ago.
Should I be considering some secured wallet?
The most safest place to store your coin is on your personal computer, that has password know by you and you alone. You can also store you bitcoin with blockchain.info and xapro, there the most safe online wallets. Most importantly safeguards your password both on your personal computer and online wallet and you are good to go.
