Halving and Blackrock

[NotFuzzyWarm]

@OP re: my asking where you came up with rewards being 0.0003BTC/day.

S19 XP 141  

Current BTC mined per day  0.0003

After Halving it drops to 0.00017

Ah.
You are confusing Rewards - which is what Block each pays (+ all fees and currently 6.25+BTC ) with what any specific piece of hardware can earn per-day. Two vastly different things.

Ja the 1/2ving will cut earnings (for that hardware) in half but that is a drop in the bucket compared to how much the ever-rising increase in difficulty impacts earnings per-machine.

In short, nothing new here... This has been the case ever since the 1st BTC was mined and Satoshi et al got other folks to join in on the fun  
Case in point - sshot of my setup back in Aug 2014
 6.42Ths brought in 0.15BTC or $90/day...

1. Is it correct to assume that each halving will result in a 50% reduction in rewards?
( If current reward is .0003 BTC, reward after halving will be .00015 ) ?

2. Is there a good calculator for ROI and estimated rewards ( per day ) that calculates 5-10 years in the future or allows an input for estimated future value of BTC ?

3. Will BlackRock and the central bankers be able to fork BTC into a proof of stake coin? ( How are changes to BTC created ?)

Thanks,

Yes, I don't know, and Yes, respectively.

The halving divides every reward from mining a block in 2, which is why it's called the halving in the first place. As of now it's BTC6.25 per block, in the future it would only be BTC3.125 moving forward until the next halving. This effectively reduces the total supply of bitcoins in circulation and makes bitcoin a more scarce, deflationary asset in the process.

I don't know if there's any ROI calculator out there as I haven't gone out of my way to find out if there is, but there should be if I'm correct, just scour the internet.

Anyone can make a derivative of bitcoin and call it theirs, it has been done in the past with bitcoin forks like bitcoin cash, bitcoin gold, and more. Blackrock creating a proof of stake bitcoin would prove futile though as PoS, while efficient, is not as secure as many tech journalist make it out to be.

Interesting question. Anyway as others already explained the best they can do is a hard fork, and then people would be free to choose whatever "bitcoin" they prefer. Let's say that seeing what happened in the past the best idea is to stick to the original bitcoin, I highly doubt the real bitcoin community would ever join a fork made by investment funds and banks, those are the main reasons bitcoin was created in the first place.

I will skip the first two questions as you have already received many great replies. I will focus on the last one.

Anyone can fork and create their version of bitcoin. We already have hundreds of such forked coins dying in the market. But if you want to make changes in the real bitcoin itself, you need to reach a consensus from the mining community. At least 95% miners need to support that change. There is a great article you can read to learn more about BIP.

Hope this helps!
