Its not a problem for me to buying the 59 bucks usb.
problem is bitcoin is banned in our country so thats why i cant import such things in my country or i cant order, its totally banned here.
thats why i keeping my funds on online web wallet.
In this case, i'd probably go for an airgapped setup... You'll need an old laptop or desktop and one or two usb sticks (one to transfer signed/unsigned transactions and potentially one to keep a backup of your wallet... The backup-usb should never touch an online machine tough!). I'm pretty sure there are no countries (except north korea) that are suspicious of somebody buying an laptop and a usb stick

Though this requires a bit of time sending your fund than using an online wallet but this is the most secure way to store your
BTC.
But if you want easier setup but still in a secure way. Installing
electrum as your desktop wallet and/or mobile wallet is good to go. Just to make sure your device is fully secured at least installed with anti-virus (windows/mac), though electrum binaries flag as a malware of most anti-virus but there's nothing to worry, you just need to
verify your downloaded electrum.
Too many instructions to follow to secure your funds, right? That's how a responsible person will do with his hard earned money.
