In cloud mining, the #power we buy is for limited time?

Really depends on where you are putting your money into.  Some cloud providers used to offer "lifetime" contracts that would expire once a threshold of unprofitability occurred, but I haven't seen this as often anymore. Most common is a contract for a set amount of time, after that you no longer rent the hashpower.

Hope that makes sense, but it really depends on the cloud company you are looking at.  Also be aware that there are plenty of scam/ponzi schemes around in the cloud mining realm - at the very least make sure it's not on this list: http://www.badbitcoin.org/thebadlist/

Honestly many people will warn against cloud mining, though I haven't had a bad experience. Generally it's easier to buy and hold though, but I'm not here to give investment advice.

Go to the terms and condition page of any cloud mining site you want to invest in. That should be your more relevant source of knowing those facts.

FYI: Cloud mining is not profitable with any of those contracts. :-) I mean what are the odds they paying you back. It's very well know and tried by many people. Do check other topics for more info about cloud mining before investing money.

there 2 type of contracts :
the first one is limited time contract,
you will get power based on your buy and they will set a limit for your contract such as 1 year,2years and something like that.
the second one is lifetime contract,which mean is your contract will run forever because it's lifetime contract.
but the facts is no matter what type that you choose or buy it has a limit.
what does that mean ?
the limit itself is unpredictable,you will lose your contracts if your contract no longer profitable,
no matter when is it,they will force you to close it or they will close it automatically.
it can be happen when the difficulty doubled and prices is decreasing a lot,while you can not pay their expense and their earning.

so in conclusion,no matter what is it.it has a limit.

Yes, thanks. It has a limit

you are newbie so you need which site you will put money on it most sites that say will give you fast income it is scam sites

Not only that with lifetime contract you will never be able to make profit old and big mining sites like genesis mining and hashflare always cancel your contract within a year because of this you won't be able to roi also , i would recommend you to go with a limit contract because that's a guarantee and has been profitable for me always.
