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?
of course, you should be considering a secured wallet because you are having a huge amount of bitcoin . if you are looking for highly secured wallet then web wallets can't be recommended for you, maybe you should install a hard wallet to your pc and make sure you won't be attacked by a botnet or any malware . I guess installing a hard wallet on Linux OS especially Tails OS is the best .
As I understand it, if you have to install a wallet somewhere (Windows or Linux, it doesn't matter), it won't a "hard" wallet because by hard wallet people evidently refer to a hardware wallet, which doesn't need to be installed anywhere (apart from putting it in some place, of course). Linux is way more secure than Windows, that goes without saying, but it still doesn't completely exclude the possibility of your coins being stolen. In other words, it is not a panacea...
Correct me if I'm wrong on this
