Bitcoin is touted as a new miracle in this century, it has become an alternative to complement the needs of financial transactions at the global level now, Bitcoin can then be said to have succeeded in establishing itself as a universal currency, because we can say that Bitcoin is very qualified as a money because it is durable, rare, shareable, and recognizable, Bitcoin became the currency of the virtual world on its way Bitcoin (BTC) transactions exploded and shocked. The product is selling well and becoming a prestige of individual wealth in the international world, however, many are pessimistic that Bitcoin will be able to shift conventional currencies both at the local and global level, will there be a miracle of bitcoin to shift conventional currencies
The way I think about Bitcoin is that it sets the precedence for digital currency, which of course, shifts away from conventional currencies.
It may not be BTC itself to act as a currency that the globe can use daily due to its limited supply and not being enough to go around, but something based on blockchain technology might be more likely.
I don't feel qualified to comment on which current alts this might be as I think we don't have the scalability required on any of the existing coins/chains, but definitely this momentum will trickle into a major digital currency adoption.
