What is a decent amount of Bitcoin you should have to make day trading worth while?
it's totally up to you. low invest means low profit and also low risk. so i think it is wise to start with low amount for beginners so when you feel confident then you can increase your amount.
But low profit isn't worth with your time , talents and efforts you did spend on it, right?
It will be worth if the guy is starting up and surely later on these days he will spend huge and earn huge if he now the technicality of the trades, And we shouldn't put some money if we are newbie since we might gonna lose our big capital for thingking to earn on these easily. Decision making is critical on these things since we need to act on what is our current stand today and don't act like a pro on tradings.
