Well, the buying the coins is a hell of a lot better than renting cloud mining services.
1. No problems with mining equipment.
2. No complications with mining difficulty (which would make cloud mining less effective)
3. You can store them wherever you want on a safe place
4. It's more profitable, since you don't have to wait in order to have these coins actually
However, if you already have mining equipment or you found some cheap rig then it's actually the same...
You got the point i think buying altcoin is much more profitable and you can gain instantly than you are investing in cloud mining site or rent a miner..
Well if you plan to buy almost 2700 euro per mining rig for ethereum 150mh/s or bitcoin miner i think it takes long time before you can recover your investment unlike you are buying a coin sample you buy bitcoin when the price of bitcoin is around $1,800-$1,900 and the price today is $2,700
You already made almost $800-$900 such a large price if just invest 1 btc when the price is low.. past few days and these days we seen the price movement is really fast.. compare just to invest our money to buy a miner that it takes few months before you can recover your investment..
Except if you can build a own custom mining rig..
