What does rollback mean? Is this coin completely dead or what?

Is this coin dead or not? I can't access my wallet for months.

Open config.json file and find this text:

"pools": [
        {
            "url": "pool.bitsum.uz:3333",   // URL of mining server
            "user": "",                        // username for mining server
            "pass": "x",                       // password for mining server
            "keepalive": true,                 // send keepalived for prevent timeout (need pool support)
            "nicehash": false                  // enable nicehash/xmrig-proxy support
        }
    ]
Put your wallet address into "user" and insert pool address and difficulty port in "Url"
After that just run start.cmd

This coin was a scam. Now I think it officially died. Official mining pool is not working any more, telegram wallet is not working, devs are not replying. Just a waste of our time

I don't know why devs requested for min price of 10 satoshi for 1 bsm but now not a single person wants to buy it so the coin became worthless

IMHO, Telegram team is about to finish development of their own cryptocurrency embedded inside Telegram itself and available to all users, so BITSUM will never be used by usual users to buy something
