Mining signatum was the worst mistake i've done , it was waste of time every day i mined more my total worth of signatum was dropping

, i am mining Zcash now and i am as happy as a baby..
I personally don't think it was a mistake. Signatum is a fairly new coin and it's developers are active. The community is great. Signatum has got lots of potentials. Also you can now stake your coins to earn rewards.
However, some greedy people are continuously spreading fud against Signatum. You should join the official discord (link in op) to meet the community and see the progress yourself.
Yes, this coin has huge anti-campaign. People are earning on it. And maybe revenge. You may never know!
Discord is much better place to get fresh information about the coin. And community is also better.
