If you see a service offer life time contracts, then know that it's a scam by default. It is so obvious, that the existing and long running cloud mining services no longer use the term life time contracts anymore. Just think about it, why on earth should a service offer anyone a life time option to keep mining? On top of that, life time isn't really life time. If you read the TOS of most cloud mining services, they will terminate your contracts if they aren't yielding anything for a certain number of days (mostly 100 days or more depending on the service). These services will do everything to terminate your contracts. If it doesn't go naturally due to an increasing difficulty, they will increase the maintenance fees significantly to achieve their goal....
