Yes indeed - I have met the founders of elta.io and tople in Amsterdam. Judging by impression, both founders had a clear vision and were able to defend some of the 'bottlenecks' in their infrastructure.
I have read the whitepaper of tople and made notes on the elta presentation (no whitepaper released yet). Both aim to utilize the broad public to shift the value-chain for investment-decisions and public works. They both seem to try to provide a great social infrastructure and they both have quite conservative profit motives. (low or no-fee)

I just wanted to know if somebody already heard of those - Generally, I have a little less trust in projects that spent a ton of money on advertisement and features within the first stages of going public.

Dear Bitcoin-Community,

I have joined your platform to ask you about a few early stage coins or developments. I obviously like to know about early investment opportunities, but I am also interested in new development that could have the potential to disrupt industries.

Let me go with those:

1. elta.io (https://elta.io/)
2. topl (https://topl.co/)
3. 3DP (https://3dp-token.com/)

Some require a little background search, but topl looks quite interesting.
What do you think about them? How do you research early stage coins? Any suggestions? 




Gr, Chris
