Do you think that 2019 will be a good year for Altcoins ? and if yes which of them will performance the most ?
May be or Not. All performance is depends on Btc stability. If Btc will stable in this year then Alt can be fly after big time of resting. But I think Not only Alt but also all crypto's time will be this year. And 2020 will be golden year from crypto. We can see another bull run in 2020. And guess the fly will be more than 2017.
Agree that it remains to be seen how it goes. Market is slowly stabilizing and any good news can start the next bull run that should continue into the bitcoin halving in mid 2020.
