I've made the same assumption about MiningHamster. They just only show the Max price so it never gets "red". You can say the marketing is blinding your eyes.
The accusation that they work together... can be..but i wouldn't bet my money on it. (lets be honest, you never know who works with others).

But:
The bot is solid and has potential, but its a "beta". The developer is answering to my questions. But he is alone, so development speed is "slow".

so kick the signal service, DYOR, and work with Whitelists/Blacklists...

guys. the devs are still active on the discord channel. its not dead. stop FUDing
