Yeah,it is our own decision and I think no one is advertising bitcoin anything and no one asked to buy us.Just people we are attracted to the bitcoin by its huge price growth in the recent days.But people need to understand about the crypto currency investment before investing on them because it is too volatile so the investor can lose the investment money too at any time so he must invest only the affordable money to lose.
Bitcoin has a huge tendency it can jump upto $5000 in a day so no doubt in that but people need to believe on bitcoin and need to hold their coins when it is falling.
