Bitcoin is a global craze. Even farmers, students, the older, housewives ... who are don’t know what is blockchain also buy bitcoin. Because there are so many new investors investing in it in the hope of making a big profit. But actually that is not investing that is gambling.  
I do not prevent you investing to make money but invest wisely. Especially do not put all the property into bitcoin and cryptocurrency. Hope people do not blindly participate in this gamble.
