Now we are in 2019, did Bitcoin make a step to be a leading cuurency?
What do you mean by that? Bitcoin is the leading crpyto currency in the market and I don't think there would be another crpyto that will surpass bitcoin. It will not make a step since it is already ahead of other altcoins in the market. It is now 2019 and it is still the leading currency despite that fact that it is been a long time since its release. It just proves how strong and patient its users and investors
Obviously, he meant Bitcoin as a currency
Not as a cryptocurrency. So it is not about making a step toward becoming a leading cryptocurrency (as you correctly, noted Bitcoin is already there by and large). It is more about conquering the fiat world. Indeed, it is hard to compete with such currencies like the US dollar or Euro, which are fiat kings in their own right. But there are other, second and third tier fiat currencies, and among those Bitcoin reigns supreme, by and large (again)
right, currently bitcoin is trying to get a place as a transaction tool which is dominated by fiat. by offering many advantages, Bitcoin is developing, and in the end many governments are busy to research it
