Matt Ahlborg (UsefulTulips.org) – Bitcoin as a Bridge Currency (EP.79)
Peer to peer marketplaces are a wealth of data on genuine demand for Bitcoin – but not in the way you might think. As it turns out, a large fraction of the volume in these markets relates to complex, multi-step trades designed to use Bitcoin as a bridge currency to move fiat-denominated remittances, especially into countries like Venezuela. Matt Ahlborg, data scientist and creator of UsefulTulips.org, has done great work compiling this data and engaging with these traders to determine what exactly is happening on these opaque marketplaces, and what Bitcoin is being used for. In this episode we cover: How Matt went from working in the Navy to pursuing a career in Bitcoin data science Why p2p exchange volume is more reliable What a massive blackout in Venezuela tells us about foreign exchange flows in Latin America How exactly Bitcoin works as a bridge currency on p2p exchanges The under-reported role of Chinese exporters in Venezuela on LocalBitcoins Matt's investigation into how Argentine capital controls are driving p2p Bitcoin volumes Why Bitcoin still dominates in p2p markets rather than stablecoins Why p2p volumes are likely significantly larger than the reported numbers

Ganesh Viswanath-Natraj (Warwick) – What Keeps Stablecoins Stable? (EP.76)
The question of Tether's influence on crypto markets has long vexed practitioners and academics. In a widely-publicized 2018 paper, academics Griffin and Shams allege that Tether was being issued collusively, effectively increasing the price of Bitcoin beyond its natural level. To learn how Tether behaves like a currency board, and to assess the veracity of the Griffin & Shams hypothesis in light of new data, we brought Ganesh Viswanath-Natraj on to the show. Ganesh is an Assistant Professor of Finance at Warwick Business School, covering international finance and macroeconomics, with a focus on foreign exchange derivatives, market microstructure and cryptocurrencies.
