After some suggestions from the community and a lot of calculations, we will be setting the new PoS to 525%. We are working with the wallet and source code now, testing to make sure everything is going to be working correctly. We can't give an exact date at this time, but when testing is complete, we will release the new code, wallet, and get in touch with the exchanges so they can update. This will result in a fork, which means EVERYONE and ALL exchanges will have to update...when the time comes. Thank you again for your continued support!
