Miners with one free/paid trial for which they have right to mine are under 2%, AWS/cloud mining today are thieving cartels sadly run by ppl that know how to hack or buy identities/debit cards from ppl in need so very poor one or drug/crack for a 5-10$, no one will run operation of one free trail that will produce you 10-15$ in few days and lots of work, but if you know how to manage and get 500x accounts and you know something about scripts and linux you can make your own illegal empire
Because of those ppl there is ZERO logic to buy legally any cloud service as ROI is not possible, its not just about BC its same with all or most CPU coins!! their profitability is always under electricity price so only thieves can mine
I have done a short run of ~80 cloud instances on my own account for test purpose and managed to mine some 10 block in ~2h, as block time is 5sec its clear that 80 instances is under 1% of whole network if you exclude home miners as most mine nothing for days, also price I would need to pay for this short run would be ~30$ as network use is huge
My home PC was mining for first 4 days and only in first 24h it manage to mine, after cloud services started mining all new block mined are being orphaned
I don`t see a point of network working in this centralized way nor I see possibility of GPU mining with 5sec block time where only miners to close proximity to centralized nodes can mine a block as network speed is the one that produce valid block not the POW work
Atm their network is centralized around large cloud services and i doubt that more then 2% of block mined are from ppl that pay for that service!, even if you have 1000 home PC/servers mining few cloud abusers which have no legal rights to use those services will get majority of blocks which clearly can be seen from explorer, even that can use multiple address they don`t care as those ppl are cancer of crypto in every way!
http://multiverse.blockcollider.org/#/address/0xbad3447d278e7583208356769a385a61509cdbddyou can also check last 4000 mined addresses its all done by few dozen of ppl
Also if anyone ask of profitability, there is almost none as block is just 16 NRG which is not main token but something as GAS on ETH, and soon in ~2 months one block will be 160NRG so daily mining of NRG will be ~2.7M
geht ja doch auch mit dem Merit System dauert zwar lange aber Sr. ist Machbar, alles andere wird schwierig...
