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?

Secondly, you can store bitcoin in CD,Memory Card.First,copy the wallet.dat file to CD and delete it from computer.
Thirdly, you can keep your bitcoin in a third party websites like exchange sites or any site that allows to deposit or transfer bitcoin.
