There's nothing necessary to quit bitcoin trading, because if you can spend more time over the observation of price movement even if price goes down, can make a profit out of it.
yes someone who is pretty good and a little expert in analyzing every movement, it would be good to make a profit.
indeed sometimes if we always lose, it makes us mentally descend, and I ever experienced it. but I have a high motivation to recover losses and finally I can get up.
bitcoin trading can be extremely profitable if you know what you are doing. However, it is also highly risky by nature so you can both win and lose large sums of money quickly. Bitcoin is an extremely volatile commodity, subject to sharp swings up and down in price with very little warning. so with good skill and keen observation on bitcoin prices you can make good profits.
