2020 will become a year of stablecoins with many very promising solutions from giants as Facebook and others. Rockstable can surely catch this trend.
That's right, if 2020 is not a year of altcoins actually, that will become a year of stablecoins. People should trust stablecoins more than regular altcoins, because they don't have the biggest disadvantage of other cryptos - huge volatility.
It may be both. Who knows, maybe some altcoin will overtake the king - Bitcoin, it won't happen the next year but may happen in a few years.
