We need to get on some high volume exchanges to succeed.
I can guarantee you that you will be informed as soon as the team has received any kind of news about a possible listing on Bittrex.
Succeed in which terms? Increase price? Adding more volume does not always increase the price. Many coins have fallen in price after being added to Bittrex. The only thing that may have an effect is the trust added to the project by being listed on a big exchange.
What actually makes this project succeed are the developers. With a software that has a very big user base (i.e. it is useful to begin with), the volume will increase on the existing exchanges until big exchanges add it for their own interest. So the root of everything, and the only thing that truly matters for increasing the price, is developing great software. That's what has been happening all the time! If you want to get rich, you have to wait until the software has reached great usefulness. That's the most intelligent way to invest IMO. Do not make yourself depend on the ups and downs of the price, while the software is still in early stage. If you want to make huge profit, you need to be patient. Everything else is purely speculative.
My opinion is on the assumption that we already have a great dev team !
