Trading needs your time and perhaps your whole day because there is increase and decrease in price of the market so you should have eyes on market price. If the worth is higher then you should never buy any coin because it could be a cause of your loss. You should have patience and do no be in hurry to make the profit at once. It will surely take time.
I guess those who are experienced in trading will not need all their day to look at the market. some traders who want to make daily profits may only trade for 3-5 hours in a day. that alone could be faster if they could get profits sooner.
the key I think is choosing the right asset and the right time to buy. That ability I think needs to be considered for anyone who wants to trade.
