Hi @ivanli, I'm new here on Steemit (just joined today), but I've been following your YouTube channel for a few weeks now, and wanted to thank you for the good work you are doing to educate the public on blockchain technology and cryptocurrencies. 

I work in the software development industry and have found your videos to be a go-to resource for a developer's point of view on this new technology.

Your efforts are very much appreciated, please keep it up!
