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?
Blockchain is really good and most trusted of users to store their bitcoins this is a number secured bitcoin wallet in the world even your going to hold your bitcoin for year's it will be safe in blockchain

just always remember and save the important things.
