Okey then i won't use my laptop for mining!
I also heard about cloud-mining.
Can i use those for mining LiteCoins?
Can you seuggest a good one?
How much will it cost per month for me to pay for resnting it and electricity and what would the profit be?
Avoiding the cloud mining site, if you're wanna for using the cloud mining site are like just wasting your money into the dark hole. the best one is trying for collecting your amount before and buying a miner tool like usb mining tool if you're not enough money for buying a large mining tool like s9.
You're correct about cloudmining: think about this fictive example:
I have a good electricity rate, and buy an S9... If i run my S9, i make 0.01
BTC/day profit... Why would i ever rent out my mining equipment for less than 0.01
BTC/day... It just wouldn't make any sense...
So, either cloudminers try to scam you, make you pay more than you'll ever make, or sell the complete risk to you in return for a small fraction of the profits... Neither of these cases are good for you (IMHO).
I don't really agree on your advise for the OP to buy an usb mining stick, nor do i completely agree on advising him to buy an S9.
An usb mining stick will probably never ROI (i did the calculation in a previous post, just to lazy to look it up). An S9 might give the OP some profit, but ONLY if he has a good electricity rate, enough technical knowledge and an appropriate place for his S9. Additional research is defenatly needed before buying any ASIC.
