I think the reason I use bitcoin because bitcoin has many advantages, first bitcoin make our transactions more efficient and faster because by transacting using bitcoin then we do not need to change our currency to the value of the goods so that the transaction can be done immediately, the second is also made into currency, bitcoin also can serve as a valuable investment asset ... the higher bitcoin's popularity is making high bitcoin market demand, of course this makes bitcoin prices soaring so we can earn big profits. Then the bitcoin's nialy can not be played by the government or a country because the bitcoin stand-alone value of bitcoin depends only on the demand of the market itself
