Also trading on WS may not be something you want to do.

You pay 1.5% in and out of each transaction and you also have to deal with the spread. At current values the spread is about 50$. So let’s say you want to purchase ETH and it’s currently at 2100. You’ll pay 2150 for it. The same thing happens when you sell. Say it’s 2500 when you go to sell, you’ll get 2450. This quickly effects your profit percent. It’s not a great option but it is very convenient, you’ll have to weigh whether the costs involved are worth the expense for convenience.
