One idea: it might be worth asking for email addresses. You already had 27 people interested. Build a quick unbounce page and get the emails so you can recontact.
Thank you. I appreciate the screenshot. Interesting; I get the feeling the tag algorithm is crucial to make it work. Not sure it's such a clear no-brainer as I first imagined it...
They answer this point on the website:
"Q: Why do you use SHA-1 in the place of a MAC?
[...] since this means still requiring at least 2^128 operations (instead of 2^256 with, say, SHA-2) to even begin trying to break this scheme, the trade-off seems fair."
Why not break the crypto (and take the money) if it's so amateurish?
""It's legalized front-running. I think it is basically evil and I don't think it should have ever been allowed to reach the size that it did," he said. "Why should all of us pay a little group of people to engage in legalized front-running of our orders?""
This videos on Box don't work very well unfortunately: I can't pause and resume a video. Every time I miss any information I have to reload the page and start from the beginning of the vid....
Otherwise, great and I like the one video I watched. Thanks.
I recommend this book: "Happiest Toddler on the Block: How to Eliminate Tantrums and Raise a Patient, Respectful and Cooperative One- to Four-year-old" by Harvey Karp.
The book actually has plenty of "tricks". Contrary to what I have read in this page I found (and this is the point of Dr Karps' books) that there are plenty of tricks that are absolutely not intuitive.
For example to avoid a tantrum you repeat to the child what he actually wants ("Jimmy wants to eat more cake") then explain shortly why he cannot and propose something else. I found this works surprisingly well. Just the fact that the child hears what he wants from your mouth seems to make a big difference.
What I find annoying is that to simply test a business idea where you need to store subscriber's email addresses you normally need to register at the CNIL for which you need a registered company which requires what is described in the article. It feels backwards somehow: you need to register a company (with all the paperwork involved) before you even know if it can work.
