Cloud mining is not profitable. If it seems like it is, the company will disappear with everybody's money after 6 months and there's nothing you can do. After all why would somebody go through all the work of setting up miners, a website, and company so they call sell you profit?
Miners don't cost 100-200k in USD. You can buy small ones for as low as $50. The large companies do have a benefit when buying millions though.
any miner u suggest that i can make profit??
The Antminer S3 is what everybody says is priced low enough that you might be able to make a profit. You need to buy 2 at once and they're 0.64BTC right now, so out of your budget. You can buy part of one in a group deal but that can be risky.
I would suggest just waiting for a little dip in BTC price and buy as much BTC as you can with the $70.
