On Binance, on trading page, if I buy alcoin using market price, will I get my altcoins right away like when I buy using card? Or will still have to wait for certain trader to respond to me?
I never bought anything thru trading. I have no experience buying from Binance trading.
When you buy at the market price, technically provided that the market isn't too volatile you should be getting your order filled straight away. There are advantages and disadvantages to doing this, so this choice is solely up to the buyer.
One obvious disadvantage is that the price might drop shortly after your buying order has been filled and then you're at an instant loss. Of course, the opposite can happen in reverse. A good way to gauge market movements is to look at the candle sticks (i.e. graph) from the last few minutes as that gives you an indication of what's going on and can better predict short-term movements.
