...I believe there will be a future for Stratis once alts turn around again. There are however a few other coins that are also active eg. Waves, One, Matic...
Infrastructure projects like Stratis and others mentioned above had seen a lot of hype and the price pumped during the bull run in the 2017 - 2018.
From this time all of them lost almost all value and only because of the recent BTC pump there is a positive impact on altcoins prices.
There are so many infrastructure projects, that developers can choose the best one which is most suited for their needs and this is a good thing, of course, but as for now there are only a handful of dapps or services build on top of Stratis or even Ethereum, which would be widely used and recognized. The most used dapp, so far, were Cryptokitties and as for today, only a few hundred people use Dapps on a daily basis. This is literally nothing and I am really worried about the future of infrastructure projects.
As I said already the price raised only because of hype and all these ICOs which were possible thanks to Ethereum. On this wave of hype, other infrastructure projects like Stratis made their way to the top 50 on Coinmarketcap, but a lot more efforts will be needed to move the price up again now or in the 2020 year. This will be possible for Stratis, only if many very good dapps and services will be finally developed and all of them will have to be very successful additionally to change anything.
The only purpose of the Stratis project is to provide a platform for developers to build on, so if there is nothing build already and the pipeline isn't full, I just can't see how anybody can think about a bright future? Please show me anything which is built on Stratis and used actually, so far I don't know literally even one usable product build on it.
