Where is dump

cmon at least to the 10k please.

mining cost is about 8-9k sats.
Mining cost was around 12-14K if you were using rented rigs .Hashrate was around 9PHs during POW.
And most of the miners must have already dumped their coins in yobit.Also before it was listed in trex almost 500K coins were staked and 10 MNs were there ,now around 300-320K coins are being staked and 8 MNs are there.
No the mining cost was around 5500 Sats if you were mining from the very beginning before any of the blocks halved. That is with rented rigs.
Later on it cost more to mine because the blocks halving were very large, much larger then the mining cost and the difficulty never seemed to change. So you could of made alot of money taking the risk mining this.
