The extraction will probably disappear
At least it will be extremely rare. Looking at the trends of markets and people who maintain networks, it seems obvious to me that we are achieving a key optimization point.
I will not bore anyone with numbers, because it may not be very funny, but just as cryptocurrencies are fantastic technology, they are still not able to process the required transactions to "take over" our economic system.
This is the case for all crypts, including Steem, which is Steem, which is at the forefront of speed and capacity. This is one of the reasons why I believe so much in this project and blockchain.
Proof of shares will be valid
It seems very likely that the energy demand in bloated block blocks prevents miners from maintaining profitability. Let's be honest, if mining Bitcoin ever becomes unprofitable for miners, then we can be sure that blockchain will fail.
For this reason, I am sure that in the future most of the cryptocurrencies will not be exploited by any algorithm aloud, but rather put up.
I read about masternods
They are not a novelty, not a long shot, but they seem to be a great way to sustain your resources. Especially that the current cryptography market seems to work as if testing our emotional strength, which is why I think I intend to get acquainted with popular offers.
And because of the reading I've been doing in the last few days, I'm wondering what other Steemians are currently studying. I have seen some good entries about SmartCash and not a great post on Pivx, which is Pivx, which I'm not interested in much, I should say.
