Is BTG Pactual launching security token on Mainnet?

BTG Pactual is the biggest investment bank in Latin America as of 2017: https://en.wikipedia.org/wiki/BTG_Pactual https://www.bloomberg.com/quote/BPAC11:BZ

Launching security token: https://www.bloomberg.com/news/articles/2019-02-21/btg-embraces-crypto-assets-by-launching-real-estate-backed-token

A development very interesting by itself, but here's a line that sparked my curiosity:

Investors will be able to buy the token through a digital platform by using Gemini Dollar [...] or Ether

Notice anything missing? Where's Rial or Bitcoin? Can it end up as mainnet ERC20???
