In his local currency, I'd guess, because someone with so much interest and eagerness about Bitcoin and its accumulation wouldn't just use $110 from their salary for buying Bitcoin if they are earning 5 figures in dollars unless they have extremely high expenses and can't manage to save more money than this which again doesn't sound possible to me.

Anyways, congratulations, OP. The very first thing I would tell you is to kindly not keep your Bitcoins or any other cryptocurrency in your exchange wallet unless you are planning to do day trading with it which means buying and selling within short time intervals because exchanges serve different purposes and they are not supposed to be used as wallets to keep your funds.

Electron isn't a bad choice if you don't have a lot of Bitcoin at the moment. You can always upgrade to a better option, like a hardware wallet, in the future when you have more funds to keep. For now, you can use Electron, better than Binance for keeping your funds. Just make sure that you back up your keys and phrases safely.
