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.
AFAIK It depends on what trading aspect you have made. There are P2P trading that requires verification and acceptance of the other user you will swap your crypto, and there is also called Trading Spot which there are users in a trading platform that places sell orders then once there are a buy order with the same amount and the same price as the sell order, then you both would be automatically traded.
Hence, If you buy an altcoin in its market price,
(in Binance) you would wait for some moments for your trade to be successful, depending on the volume and buy/sell orders of the crypto in that market.
