@iamisti,
Lifetime profit means they will keep mining and paying out as long as mining remains profitable. Miners will regularly be replaced by re-investment miners.
They have some of the lowest mining costs in the industry. Way better than hashflare, minerone etc so relax. Only worry if BTC collapses and never recovers. I personally don't see that happening.
Their tokens are so cheap now on token.store FYI. Perfect time to get in if you expect a bull run.
