It's real. But you can't go buying it as there are times when to buy and when to sell like stocks. Whoever bought must get profit is not true as my on friend invested 25k and lost most of it while another friend is making good profits.
Don't jump in crypto just because others are making good profits. There are many currencies in crypto and not everyone knows which one to invest in as it's all unpredictable for small investors. You have to buy the right currency at the right time dips to get good profits.
or are you looking into mining?
