What is a decent amount of Bitcoin you should have to make day trading worth while?
For me any amount as long as you are a professional trader then you can surely earn money daily. No matter how much your money is when you dont know how to execute well then you will loose money, daily.
Trading is the most favorite and respectable profession throughout the whole world and all big traders are very rich and has a quality of patience and honesty. I am personally like trading very much and also doing trading of bitcoin and I am very happy in trading.
