$ABST main usecase at the time of writing this review is for making transactions. There are a lot of uses claimed but almost none are in existence or really implemented yet. In my opinion the project is still kicking off, there is no solid usecase and little exchange support. $ABST "looks like" just another coin with a whitepaper.
With that in mind it still catches my eye the unique usecase that they claim, to use the project to connect Virtual reality users and content creators, giving them a safe environment to build and share their work. Again this hasn't been implemented yet or maybe hasn't been made public but it sounds good to me.
Would I buy $ABST?
For trading maybe, for now the project does not seem complete enough for long term holding.
