You all say that this is a bad idea. But what will you do when all Bitcoin coins are mined? Which blocks will the transactions then fall into?
This is a compulsory necessity. And so that the price of bitcoin does not fall, POS can be set at 0.1% per annum.
I see people like you connecting PoS with the inflation. PoS is just a consensus algorithm, it has nothing to do with the monetary policy.
You can have an inflation using PoW just as well, and you can have PoS without inflation. They have nothing in common.
There will be blocks in Bitcoin after last coin is mined as well and miners will be only earning from the mining fees of the transactions, which should increase by that time in value.
Does anyone think BTC possibly switching to POS? How can it evaluate / score the stake factor?
This is very bad idea.
Why would you give more money to institutions like FBI? They are owning thousands of millions dollars worth of confiscated bitcoin. And POS implementation will require a hard fork which is one very risky intervention.
You make a good point. Governments size a lot of Bitcoin when they raid. This could give them power to censor Bitcoin as well after they raid few big dark markets.
While it would be a whole lot greener, the miners would never let this happen anyway.
I think it's about time we addressed the environmental impact mining is having and will continue to have into the future unless a better algorithm is implemented that would not require such vast electrical resources yet still produce valid work that can be validated.
I am afraid that Bitcoin will always produce a lot of electricity. Cost of mining rigs are usually not the limiting factor for big miners, but the actual power that they can get into the building. Some real world resources need to be spent to secure the network, this is the whole point of blockchain, figuring out a way to bind Internet presence with the real world by giving problems that requires real world resources to be solved and it does it all in a decentralized manner. I know this is a pretty radical point of view, but I think that PoS blockchain is not a blockchain. It simply doesn't have any limiting factor that keeps the attackers from spamming the network with malicious votes on what the next block will be. This is better known as "The nothing at stake" vulnerability.
Now we might make a real world resource be something other then electricity, like hardware, but it is the same point. The point is that we need to make electricity production ( as well as all the other productions ) more ecofriendly, not trying to cut costs on security.
