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.
It depends on how you planned or what kind of method you bought the altcoin.
If your way is spot trading, it's automatic, once your bid and other's order has matched(depends in the volume to that value), your trade will be automatically done.
Your waiting time is just if the price of that altcoin went to the price you've set.
But if you buy it directly on it's current price it's instant. Your balance should be updated then.
