Hey, I know late reply.
But I'm actually a customer at MeaTec & stakecube who uses MeaTec as a mining provider for their cloud mining service.
I own BTC, Dash & ethereum mining all through MeaTec. Profits aren't anything crazy, mining speeds aren't perfectly consistent and it isn't perfect. But that's mining. My current roi is looking like it's around 50-60% yearly so not bad at all.
Personally I think they'll be around a while and continue the great work they've been delivering. If your looking for a good provider I'd recommend them.
