The trick please note 7 to the following factors:
1. No public mining address / no user selectable pool.
If there is cloud mining that does not allow you to know where he is mine, address bitcoin address their mines, or the user can not choose the pool and the types of coins mined (ex: scrypt, x11, ethash, etc.), cloud mining could be suspected, there is no reason to hide bitcoin address, because from there we can know whether the pool can block bitcoin or not. Not perhaps a pool that does not get bitcoin block can share mine output.
2. No endorsement from any asic vendor
Mining equipment providers / ASIC vendors will be happy to endorse miners, why? because it can be as free advertising for providers of these tools. So if there is no reply for signing off on cloud providers mining tool, could be suspected they were not really mining.
3. No relevant pictures of their hardware and datacenter
Kalo has no mining cloud data center, tdak can show their mining equipment, mining and they use what tools? keep in mind that the FIGURE can be manipulated, so if only the image there is evidence that not only got them, can just keep fake.
4. Open ended IPO / fractional reverse mining risk
Although that makes cloud mining is the hardware provider for the miners, keep in mind that they can not sell hashrate instant and unlimited, for what? Because the hardware ordering, receiving, setting up, and running it requires substantial time instant.
If cloud mining, after making a purchase, it will immediately be mining, especially hashratenya unlimited number, and you also do not know how many total hashrate them, hired how, the rest of the how, it can also be suspected.
5. Referral programs and social networking
Make it as a matter of mining cloud fortunately very thin, if they meberi sale to you in the form of referrals are very large (above 10%) could be just a scam. Referrals diiming lure is similar to a ponzi process, so be careful if its mining cloud gives a bonus of up to 10%. where profit even go bankrupt.
6. Anonymous operators
You have to know, who is managing the company, where real, if in its whois not protectable, and there is a real address. If no, if there is anything that is liable whom? Want investments suddenly evaporate?
7. No exit strategy
If we had the lease, then the lease can not be sold to the results of other people / providers, carefully trick of cloud mining scam that money / investment we can not run away anywhere.
8. Bonus point for "guaranteed profit"
While only bitcoinmaker.ch promising this bonus. If they promise big profits, for example above 30% it is clear that going ponzi.
Having regard to the 8th of the above, we can see whether your mining cloud it's a scam or not;
Example:
Scrypt.cc, have 6 points from 8 categories of mining scam cloud over the
number of his points: 1 + 2 + 3 + 4 + 5 + 6 => 6/7 = seems ponzi, carefully scam.
The smaller (eg 1/7 or 3/7) is still somewhat safety. but remember though tantalizing, but not necessarily it can make such an investment is a good investment.
Cool...
