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?
Maybe for you it is not a large amount of bitcoin but for me and for a good number of users here it is not a small amount of bitcoins.
I would suggest you to buy a hardware wallet, maybe a trezor or a ledger nano S or hw.1(it is the cheapest one), they are safe enough but you can use also paper wallets but hardware wallets are more user friendly.
i still can not wrap my head around for buying a hardware wallet. in my opinion it is not yet worth it for me to pay $100 (or less for some other producers) just to hold my bitcoins as long as i can make a perfectly safe cold storage on my own and then spend from it the same easy and safe way.
