I know of course about this but still what is the main use case for Decred? And if there is any then who is actually using Decred for this purpose? I hope it is clear enough?

We all know that experts assume that only 10% from all cryptocurrencies will survive in the end and the most important thing for each altcoin, token or any other cryptocurrency is to have a use case or at least to find its place on the crypto market like BTC as the safe heaven or XRP used for transactions because is fast, cheap and scalable.

There are already 3000 altcoins so 10% would be around 30 cryptocurrencies. Only so much will stay and that is why we have to start to ask the right questions and think properly about it.  There are many alts that are dying actually. Let's take all masternodecoins which on the hype of high ROI boomed in 2018 and today almost all of them lost 99% of the value.

We have to rethink if a particular coin is actually still needed at the end of the 2019 year and what will happen with it in 2020 and later?

Just look at all infrastructure projects like ETH, Waves, Wings, Stratis, etc. In the hype of ICO and Dapps building they also boomed but to be honest there are no Daaps which are known and widely used, additionally ICOs market changed and now we have IEO and in 2020 there will be no ICOs anymore.

So tell me please who is using Decred actually today and for what?
