I do not advice you use manual trading, the rate of volatility of cryptocurrecies are high now. Therefore, I advice you use trading robots. Trading Bitcoin and other crypt I currencies is very profitable now. Moreover, bull run is fast approaching
I will disagree on this, what we need is source of knowledge, great news ahead and upcoming developments.
That is the basic needs we have to do the trade. once we know that there will be big movement (in better way) we should buy and hold for a bit.
Or we should get the coin and set a sell price in the market.
