WARNING DONT go to Xtrapool! WARNING
I noticed on my pool that some people got the same payout address. I removed those addresses from the accounts and notified the ones that were affected. I asked everyone where they mined and all say Xtrapool.
Please stay away from them!
you are right... recently we saw that several pools are scam in this crypto coin system. they either steal their own miners account or try to break into the mines other pool accounts.. or maybe both :\
They login on the accounts in their database, they dont save your password with encryption and then they use an automated tool to empty these accounts on all the pools in this network. Please use different passwords/ usernames on all pools!!
