Wow, I see two investment institutions that have invested in Sentinel Chain, and the success of the project is essential.
The private sale had been oversubscribed and right now it is doing Proof of Support. It can be as simple as tweeting/sharing a fb post about Sentinel Chain to your followers/friends to as huge as linking Sentinel Chain to major crypto influencers.
Of course the greater the contribution, the more allocation will be given.
I made a video about the Sentinel Chain. I have 1,200 subscribers on YouTube, so I got an individual cap 3 Ethereum.
