It looks like another cruel attempt to advertise your scamcoin.
DeepOnion uses PoW alongside PoS, so I doubt it.
when at the beginning everyone around the world could with his CPU mining there was 0 risk to have 51% of the power in a single area..
It still would have been more efficient to buy CPUs in bulk and have drastically larger facilities, while mining in a location with the lowest possible electricity costs.
There is a risk in the fact that BITMAIN sells a large majority of mining equipment, because they therefore have access to machines cheaper than everyone else and have a lot of profit to spend on those machines, but if it was still CPU or GPU mining then it would still be just a few companies selling those.
