There is nothing in this world with which everyone would be happy. That's why we should not advise others to buy Bitcoin. They can buy at a peak and than panic sell with a loss, and although they could wait some time and be in profit, they will be mad at you because they lost money following your advice. I personally think that BTC is a good investment, but this occupation is not for the faint of heart. In some cases you should have the strength to hold calmly while seeing that the price is going down day by day.
