Day Traders : Pros and Cons of using a desktop or hardware wallet?

[starzou]

I know most of you transfer your cryptocurrencies to hardware wallets such as Trezor RIGHT AFTER the trade was done. But for those who do not possess an hardware wallet do you use a desktop or iphone wallet like EXODUS or Etherum? There are dozens of coins that are not supported by any wallets so you must leave the currencies on the exchange (Binance for example) right? Let's day you are in the subway and you want to sell your Ripple that sit in your Toast Wallet. How do you make a trade?

Also, aren't the withdraw/deposit fees between your hardware/desktop wallets expensive as you repeat this operation often?

Thanks a lot
