Only STEEM has the community and it takes years to build community and ecosystem.
Remember the DApps are the future and if any project that looking to build a foundation then they should use STEEM and then release SMT or move to different blockchain... As long as they don't betrayed Steem community like Dlive did.
I wish all the best to Minds and I'll be happy to see if they do AirDrops for Dtube users :)
Also in the future the Dapps can me run on any blockchain like we've apps that we can use with IOS and Android.
For me as I tend to think in years.. (long term) we'll have many killer Dapps will be survive and most will just merge together. like Facebook bought Whatsapp and Instagram..
