Argentina peso lost 60% value in 2018, next to bitcoin(which I think it's a scam) which lost 80-90% in 2018. First there were talks of massive gains of bitcoin, then there were talks of chain-links and ICO, a huge scam was brewing in 2017, finally (virtual currency) burst in 2018. The 3rd currency which lost massive value is Turket lira, about 30%. However, Turkey lira devaluation is very different from that of Argentine peso, things in Turkey are 30% less now if you have dollars, unlike in Argentina, price just shot up in pesos. If you like to visit Turkey, staying at 5 stars hotel at price of Telos, this is the time. 2019 could be the year the global economy is transitioning to recession. Sorry for the bad news
