RE: Think I'll Just Buy KOIN Instead...

Renting servers was crazy profitable the past days (that is assuming one dumps at the current price of Koinos as many large miners did), so it's not surprise that it's getting more competitive. At this point 25$ a day can buy a server with 74 mh/s which still mines about 1400 Koin per day with average luck, but not long ago it was closer to 10000 and in the early hours even more. These servers are paid by the hour, so it was a pretty safe bet assuming the price of Koinos doesn't go below 0.01$ and one doesn't have terrible luck. Note that these servers paid per hour are about twice as expensive than if you rent your own dedicated server for 1 month+, so I except that competition will keep increasing even after those are not profitable anymore.
The thing is, mining on consumer hardware is still profitable if you set a really low frequency (like once a week). I first thought that this would mean getting less rewards since by the time you find something on a low frequency the competition will probably be even higher, but actually it only saves you fees, it doesn't impact the Koinos reward since it's just pure luck and if you are lucky to mine a week's worth of Koinos today that would be much better than mining it once a day over the next week. The only thing is that it can get frustrating since you don't see coins coming in as often (but when they do, a lot of them!)
