Honestly I wonder about what is DeFi, many sites (cryptocurrency news sites) make it as headlines news that I have been read and it's quite popular.

But, honestly --again-- I prefer learning the basic concept about blockchain such as BTC and Eth. It's quite complicated than I imagined. Specially for me who doesn't have computer literally background. Also I quite interesting with @blocktrades explanation about second layer on Hive.

IMHO, I think DeFi is another way to give opportunity to public and give easier way how to invest in cryptocurrency.
