No, almost all are like scam sites. Better to keep in wallet and get interest. EOBOT seems nice and is old, but I don't trust in them to invest, and somewhere on this site I also read that they are kinda scam or use ponzi schemes, so really don't recommend you to mine in cloud mining for now. You can use EOBOT faucet feature to get familiar with as mentioned above by @maeusi, just for fun, but don't get serious into investing.

How come you guys are getting so low hashrates where as I'm browser mining from a very lower CPU G2020 and getting an average 25H/s on both chrome and firefox
