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.
Yes installing a wallet in your personal computer like electrum is one of the ways that you can call safe but online wallet is not. As long as you don't have the
private keys it is not yours, this situation is not different when your money is in the bank. Online wallet is just good for storing small amounts but never with huge
amount like what OP has. This should be kept in a cold storage/bread wallet/hardware wallet.
