If they are doing something, they could have done it before when the price is not this low and the volume is very low as well.
It's ATH was over $1 -
https://coinmarketcap.com/currencies/patientory/.. and the price now is only $0.007, no chance, this is already dead.
Even though they added 3 new exchanges last month, it doesn't seem like they will make the price go up again because it seems like people/investors are starting to forget about this project. Even the trading volume is very small, so it is very likely that Bittrex will delist PTOY one day.
As per my observation, not only on this project but with other projects that I have invested also, even if they will add a lot of exchange but such exchanges does not belong to the top exchanges in the market, it will not influence the traders to trade the token or coin, and that's what happen to this project.
Honestly speaking, only Bittrex exchange made this project popular, but since Bittrex exchange popularity is gone, this project also struggles.
