Very shortly, it's not advisable and it's not wise at all. Unfortunately, majority of cloud mining sites turned to be scam and many have lost a lot of money so be careful.
There are so many such sites but only few of them are legit which is actualy hard to tell so you don't need that risk.
YOU must never invest on any mining site. it is just a scam in a long run. or some days.
If you will have your own mining rig be sure that your country collects cheap electric bills.
Mining rigs also have high maintenance, you must keep the place cool (airconditioned) if you think this is really expensive.
just buy some bitcoin and rest it on your wallet.
I would definitely not advise anybody to invest in any sort of cloud mining site whether it be a legit site or not. Mining crypto currencies is surely a good thing and a good method to earn some crypto but it's only good when done via the traditional method. Cloud mining wont result in any worthy profit since nobody would give you free money just for doing nothing. It would be 10x times better to just buy any coin and hold it than to invest in cloud mining sites. Besides that, 99% of the cloud mining sites are fake so there is just no point in giving away the hard earned money to some scam sites.
Thanks for advising, learned from the expert hehe. So now I would never take the risk to invest in any cloud mining site wether its legit now that I know I'll never get good profit by investing in that kind of platform to earn bitcoin but rather to buy some altcoins hold it and wait til the time its value rise up.
