The matter there to achieve that is don't buy when there's a hype since instead of you gain something the result be negative since you possibly bought your bitcoins at the peak at that moment. The more vigilant we are in the movement of bitcoins the more chances for us to multiply it so better teach our self first not to be greedy and learn how to do a day trades since for this we can earn a decent volume and the market is perfectly fit for it right now.
That is, we need to analyze before we do something. To prevent the greed that will always come is by controlling ourselves, so we don't feel overconfident about what we got before. When we can have self-control over ourselves, we will know when to make a profit and when we need to leave the market to know when we should hold bitcoin and when we need to sell bitcoin. We don't have to follow other people who feel they can make a big profit in the short or long term because maybe they have high skills to make them have that chance.
