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.
Bitcoin dominance hits 70% now, i think now is the maximum and this number will only decrease so altcoins will begin to rise comparing to bitcoin.
