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?
Yes, when you begin to accumulate bitcoin then it is the moment to consider securing your bitcoin in a better way since a hacker may try to steal them from you, good options are hardware wallets like trezor, paper wallets or even a desktop wallet in a computer that is encrypted and that does not go online.
