It's the best day of the week, Sunday. NFL, food... crypto videos.

Here’s three videos I checked out today, worthy of a share.

The first video is Peter Todd presenting in Prague in a talk titled “What does the ‘blockchain’ actually do. Peter Todd is a Bitcoin Core developer and known for his work on open timestamps.

The talk is a bit technical but Peter goes over digital signatures, comparing them to a wax seal, and then goes into SHA256 and mining. In the Q&A he gives his thoughts on B2X. You can watch [here](https://www.youtube.com/watch?v=WYMMeqXVEYo&feature=youtu.be) or below.

The next video is from Dr. Julian Hosp of TenX (PAY) titled “How to get RICH through ICOs – Data & Facts!”

Here’s the rub, Julian doesn’t invest in ICOs. But his friend does and he took a $1 million ICO fund to $95 million. There’s a secret behind the gains, find out in the video [here](https://youtu.be/mmdHyco3SAE) or watch below.
