I'm really worried about Blitz.
Bittrex became the only exchange.
I realize that the registration fee to a new exchange is very expensive.
But if not trying will be bad for the progress of this project.
Bittrex was always the only exchange, the trading volume is good, no danger of delisting, the related projects, the Viral Exchange and Stratis, are quite healthy,
so calm down - there're no reasons to worry

if you have problems with the wallet connections/syncing, make
blitz.conf file (in the same folder as the wallet.dat) to add nodes for syncing manually, paste the following inside the file:
addnode=2ea3tcv2an2dfrdx.onion
addnode=2ea3tcv2an2dfrdx.onion
