After seeing the whitepaper of the MASS project I think we should consider because this project has high potential to develop in the future, although there are still many old projects that we can currently invest but mass coins are also one that must be relied on, especially now there is a bounty kompanye that supports the project of course this will add to the appeal of investors, And currently the price of MASS is very good because this is a new project present.
You are right, we need to invest in coins only that have solid background and can go up in the future (though there is no guarantee of future). MASS has proved that it is here to stay by its price and huge community.
Dont just blindly follow a coin based on its previous history. MASS social media channels are silent including this thread. It may that owners may have abonden the coin after getting necessary profit. You better DYOR before investing in any token.
