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?
No matter what wallet you choose, remember that your bitcoins are only safe if the private key was generated securely and remains a secret. Choose a storage method based on your needs and your wealth. Theres no reason to ever store a large amount of funds in a hot wallet.
