So far, Elon/Tesla: 1. Bought a bunch of Bitcoin. 2. Announced they were going to accept Bitcoin, sending the price up. 3. Sold a bunch of Bitcoin to pad out otherwise poor earnings, citing their goal of "testing liquidity of the market." 4. Announced they were going to stop accepting Bitcoin, sending the price plummeting. As though he didn't know the environmental impact a week ago? As though he didn't check for liq…

Hope we now can start a proof of stake cycle. Peercoin is dead. What other proof of stake viable currency is there? Only when the energy impact of crypto currency is dealt with will i indulge in speculating that it can be a net good for humanicy

Polkadot / Kusama (by the original CTO of Ethereum Dr. Gavin Wood) Nice recent interview: https://www.youtube.com/watch?v=KAa1vKyVR5M

Polkadot/Kusama are amazing projects, but not designed to be used primarily as p2p currencies. As much as I have some issues / doubts with Cardano, I still think it's the most viable PoS cryptocurrency for mass adoption right now. ETH2 maybe also, whenever the transition actually happens.

I see this as market manipulation. Tesla hasn't suddenly become aware of information not available when Tesla initially announced they'd accept bitcoin as payment.

That is anarcho-capitalism to you. Even though I'm a libertarian leaning, I still think we should put a tax from CO2 emissions on crypto transactions. Something in range of 300$ per tonne of CO2. So with bitcoin emissions at 0.5T per transaction, it would be somewhere around 150$ per transaction. And to cash in on bitcoin you should be required to document the whole history of bitcoin you own.

Is that not market manipulation?

Proof of stake is validation-by-the-rich I like https://chia.net , even if hackernews was just panicking about a harddrive shortage (proof of space) I can't accept that playing bingo on terabyte drives will ever be profitable enough to buy a data center for it. Anyway it's the programmability (chialisp) that is really interesting.

You used to be able to mine Bitcoin on a CPU. Then a GPU, now it takes warehouses full of ASICs to do it profitably. What's stopping Chia from doing the same thing to the storage space? Adoption. I don't like Chia, and I don't want other people to like it either.

> What's stopping Chia from doing the same thing to the storage space?

The gobsmacking amount of HDD supply on earth. For now people are burning SSDs to create the plots (1TB SSD can probably create a petabyte of plots to "farm"), but if you have that petabyte of storage space you're keeping online 24/7, do you suspect playing bingo to win crypto tokens is the most profitable use of that memory?

How the economics shake out remains to be seen, but I think they have a solid vision that farming can be just rewarding enough for people to use old harddrives, not profitable enough to burn NVMe sticks.

eg: I farmed 2 coins running an old thinkpad and a network drive for a month so far. Worth ~$2200 at current rate. Nice profit, but probably not buying a new thinkpad to dedicate to it.

Meanwhile they started accepting Dogecoin at SpaceX just couple of days ago . Dogecoin has exactly the same energy spending incentives as Bitcoin. The whole set of actions doesn't sound very logical.

> Meanwhile they started accepting Dogecoin at SpaceX What does that mean ? That SpaceX sells LEO trips in dogecoin ? Or that the coffee machine takes dogecoin ?

The actual flight is purchased with the Dogecoin currency.

When Tesla announced the initial move they received a huge amount of push back for the environmental concerns. And it didn’t look good for an EV company of all things. There is a trend I’ve seen of a company making a decison, everyone hating on them for it, then they reverse the decision, and they are still criticised. If a company turns around and reverses a decision citing the very reasons they were criticised for…

>I mean, isn’t this exactly the behaviour we want to encourage?

I want to encourage 'corporate flexibility and social accountability'.

I do not want to encourage market-whale-individuals to attempt one-person pump-and-dumps on small(ish) global markets and further market opportunism & manipulation.

Personally I believe that the decision has little to do with environmental impact; I think that the btc opportunity is beginning to dwindle in various ways, so the focus shifts to other *coin markets where they can profit similarly using the same or similar tactics.

BTC specifically is made out to be the boogeyman so that the excuse doesn't disallow similar behavior with other coins in the future. I fully expect similar reasoning with DogeCoin when that opportunity dries up and they move to greener pastures for the third time -- inevitably when profit margins are greater elsewhere.

Well, they might saw the backslash in environmentalist community, that used to be their main supporters. That's imo a pretty big sudden information.

You don’t think they knew that going in?

I think a lot of people are aware that bitcoin transactions have an energy cost but haven’t sufficiently gone down the rabbit hole of quantifying exactly what that cost is.

I don't see why people would bet the future on something that is thermodynamically doomed.

According to Satoshi, dependence on thermodynamics is a feature to prevent centralization.

Doesn't seem to be working so fine now, is it?

Also I wouldn't put behind well financed groups that hire PhDs to find a way to accelerate the PoW enough to gain a significant advantage (as in, ability to centralize the blockchain).
