I think Bubbletone is the pioneer and hopefully will start the first public blockchain in telecom before 2019.
Here are the reasons:
A: MVP (https://www.youtube.com/watch?v=hlUXrBEw3y0)
B: Blockchain is developed on Graphene (https://github.com/Clementvale-LTD/blockchain-telecom.graphene-core)
C: App is developed and recently updated (https://play.google.com/store/apps/details?id=com.countrycom.bubbletone&hl=en)
D: Millions of dollars collected to fund the idea (https://icobench.com/ico/bubbletone)
E: A new operator established (https://bubblefon.ru/) and currently is working
F: Team tirelessly present the product all over the world (30 event just in 2018)
G: Right partners are selected (https://www.lightreading.com/oss-bss/bss-(inc-billing-revenue-assurance)/nexign-bubbletone-to-develop-blockchain-based-bss-system/d/d-id/745346) & (https://www.horizoncomm.co)
I understand from the above evidences that hopefully the team will successfully start the blockchain before 2019 and maybe the roaming free service in 2019.
The effect will be huge, and the price could up XXX even before we get any announcement, so if one wants to invest I believe today is the right time.
Having a good idea and building a team then implementing, promoting, running the project are totally different things, all know how this is hard to do that in current bearish market.
Keep Up
This Q&A is a little old but still worth https://www.youtube.com/watch?v=k8CUOFtlzQI
Investing on a new idea always is risky but if the idea succeed investors will gain a lot more.
Obviously this project is one of big potentials anyone can find today.
Market don't know about it, but after releasing the first telecom blockchain, situation will be changed.
Although price is dumped I feel confident.
