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?
You really need to consider getting a more safer wallet like electrum or trezor and do not put all your eggs in one basket,I understand that you are just want to buy and store for future wallet so you don't need an online wallet but if you decide to have one,only keep a small amount.
