What is a decent amount of Bitcoin you should have to make day trading worth while?
I think that for you to be able to trade well, there are a lot of things that you have to pay attention to in terms of knowledge, technique and market information. We can see that the price of bitcoin in the recent period has not changed much and is gradually going and showing signs of slowing down. So I advise you not to trade bitcoin at this time, want to trade bitcoin you have to spend a huge initial money that it brings you very small profits. So if you really want to invest in bitcoin at this time then buy and hold for a long period of time then you are profitable.
Not at this time but with bitcoin, I will never ever suggest trading. Trading is a proper profession and it needs a lot of attention plus technical knowledge. Bitcoin is not something with whom you can take risks because once you have lost this mighty coin.
It is not easy at all for you to regain it especially in trading. Keep in mind that trading should be done with altcoins because they are not much expensive and easy to collect as well.
