Greta loses the fight if they all open their coal power plant.

Biden had a deal with Iran I guess that will make up the Russian oil and gas. Saudi seems to be hostile to US these days after Biden criticized them. I doubt it will be as cheap as Russian gas but it will make the business run somehow. What is to be speculated recently was the EV cars to be valuable but still, it needs energy. And energy comes from gas still despite having batteries.

4) Use option 1 - 3 altogether

And now Russia has finally stopped shipping gas to Europe, which makes European countries finally constrained by gas consumption for factory needs. It turns out that the impact of sanctions against Russia was actually retaliated by stopping gas exports, we know Russia is the largest gas producer in the world and even Francis is the country that buys gas the most from Russia, now he appeals to its citizens not to panic and will immediately take alternative actions using coal. Closing each other's economic gaps has an impact on the instability of other countries. And one thing, non-block countries like me are experiencing the impact of the invasion which is almost a few days where we live the internet is completely down.

That's not how sanctions work.

Let's imagine the sanction on Russian gas/oil. If Europe is starving for gas and aren't allowed to buy it from Russia they will not buy it from Russia. Cryptocurrencies don't even come in! Similarly if the starving European countries decided they have no other choice to buy Russian gas they will buy it again there is no cryptocurrencies involved!
That's the same with anything else that was sanctioned.

What bitcoin can help with is when regular people are being sanctioned by the orchestrators of the financial terrorism, can easily use a currency that nobody can take from them or can dictate where they can use that money.

To make any change mandatory, you would need to at least make old transactions non-standard (not invalid, because you need a way to move old coins, close old channels and clean up the whole mess with some help from miners). Then, if making a private transaction would be standard and everything else would be non-standard, you would reach your "privacy by default".

But if you don't want to force users, then sidechains/federations/LN-like-channels is the way to go, where only some users will have that privacy. You cannot force everyone, because for example you cannot force everyone to use CryptoNote today (so, the set of anonymity is still limited by the number of altcoin users, no matter how good that altcoin is).

I think the same way as well, using cash will be a reversal of the trend that we are seeing of people preferring electronic means of payment over using something more physical like cash.

Besides even if cash can be used at will it is still printed by the government, so in a way you are still part of their ecosystem by using it, so if someone is interested in resisting the oppression of banks and governments then using something like bitcoin makes the most sense to me.

Now is the crucial moment to show if your theories make any sense, because Russia is now in a situation where it will have more than enough resources to mine Bitcoin, and sanctions have no effect on them if we know they can import mining devices from China. But I still think that the earnings and all the other benefits of such an operation are quite insufficient for the situation in which that country finds itself.

Besides, do we want this to happen at all, given what is happening in Ukraine? I can already see the headlines screaming from all the front pages "Putin uses Bitcoin to avoid sanctions". Do I even have to say what would happen next?

Buy every dip and sell it when it goes high? Well, it is something manageable but somehow we look also the market trend and not just of the price itself.

It gonna be a big loss in our part if we keep buying during the dip and never have any returns after then. We should be smart in making decisions and to understand what was the market did.

[n]Do you have any calculations or graphic analyzes that prove what you are trying to say here[/b]? I don't know, but many are still optimistic about 100K USD before the end of this year, and given the current situation, we still have promises of good volatility.

Personally, I see the best opportunity to buy when no one wants to invest, fear prevails, and everyone starts to worry about the price, then it will be a perfect opportunity to buy and sell.

So far we have not seen a correction of 80% and therefore it is difficult to rely on historical data.

Lightning Network basically update HTLC state on each transaction, so i don't see how it's possible to implement MimbleWimble, RingCT, or zKSNARKS. But it's possible if you implement in on side-chain or on-chain.

The U.S. are looking at Iran for oil, but it's not clear to me how natural gas will be replaced. There's a lot of infrastructure considerations involved. I think most countries are just going to have to deal with the high costs and hope the energy supply from Russia isn't curtailed any further. They might even use it as an initiative for green energy but that strategy won't impact anything short term.

Who will Replace Russian Gas Supplies to Europe?

Monero's RingCT (and ZCash' zkSNARKs) scale poorly since you never know when outputs are spent, so you have to treat all outputs as your UTXO set.

One Taproot address and a new opcode (that can be one of existing OP_SUCCESS opcodes) can solve that. For example: you can choose some H as some public key, where nobody knows the private key. Then, you can create "r*G+v*H" as your Taproot address. You can accumulate inputs by aggregating Taproot public keys. Later, you can spend by script and reveal your "v*H", then your script would be your "r*G". So, your v-value can be your amount in satoshis, and your r-value can be your public key (or even another Taproot address, if it would be possible to make it recursive somehow, we have MAST, so it may be possible).

So, you would send your coins to "r*G+v*H" Taproot address, you would reveal your "v*H", and "r*G" would be inside your TapScript.

Switzerland is a high ranked economy by GDP, and one of its city's being linked to bitcoin is a huge step in the direction of adoption.

This sort of news reinforces bitcoins utility as a currency and store of value and even though it may not have significant impact on the market value, it very well could impact how institutions and government see it, triggering more adoption.
