Well to store bitcoin the right way and learn everything that you should learn before purchasing the first time is quiete complicated to be honest.

You can send transactions for a very low fee if time is not an issue. Just reserach how to set a specific sat amount for the fee.
Still this is not how it should be, but at this point I think Bitcoin has forever lost its ability to be usable for small transactions.

The best way is to DCA and thats it.

Yes Bitcoin price went up after Coronavirus.
No Coronavirus was not created by Bitcoin whales.
People still laugh about you in this moment because of this stupid assumption.

What is not practical for them however is the fact that Bitcoin will be more and more inaccessible to new people, since the cost of sending bitcoins will simply be to high for a usually small first investment. But yes it is not surprising that also the Bitcoin community will at some point drown in their greed and there will be a new innovation that will flush Bitcoin away.
As they say at some point you will become your own evil if you are drunk enough in your success.

It depends on the wallet software. I have tried something similar with blue wallet and every time the transaction was dropped from the mempool it was instantly resubmitted automatically. Eventually after 6 month it was confirmed when there was a timeframe where fees went to 1 sat/vByte.

So you can simply try it and wait for it to get confirmed. Just check that it is not thrown out of the mempool and if it is just resubmit it.

It will not work at this moment, the transaction will stay in the mempool unconfirmed. It will be thrown out after around 2 weeks and never be confirmed.
Right now you will need at least 6 sat/vB.

This SEC employee is very wrong in my eyes since he does not understand bitcoin correctly. Bitcoin is not dependent on any kind of exchange or other institution. The users can go to another exchange in a matter of hours if one exchange would abuse their power. This is different in the fiat banking system. If you understand that you will understand why Bitcoin is decentralised and fiat is not.

Lost coins in theory are like a donation to the other bitcoin holders, but since nobody knows what coins are lost I think there is not rally a impact at this moment. The only coins that are really lost are OP_Return coins that were burned.
People for example always claim that around 1 million satoshi coins are lost. However you can never be sure of those coins would at one point move again and suddenly be sold. So I think because of this risk those "lost" coins are not really a push for the price.

Thanks for clarifying that! In my opinion you can not complain about this because you then get exactly what you paid for. Yes it would be nice to have more features that were not available when you bought the device, but you can surely not complain of the company does not give you those features, since they never said that they would.
The only thing that I could imagine that would be very bad is if some newer wallet versions would not recognize the transactions from the older ColdCards, because maybe some kind of format change. But that does not seem to be the case in any near future.

Bitcoin is still decentralised but it has failed as a currency because of the decision to not upgrade the block size. This is a pretty easy fix for the future but before it is done bitcoin is crippled and can not be used in the intended manner.

This is not really an easy question to answer I think. If you want to get an answer with 100% certainty you would need to go to court and see what they tell you, since there are always at least 2 possible solutions to law problems. I think however that this is not really an issue with coldcard right now and there is probably no real need to discuss this more, if there are not really people that issues with their ColdCards software.

As far as I understand all the Coldcards form MK1-MK4 can still be used safely as of now or is that not correct?

I am not sture if this information is still correct, but as far as I know bitcoin core does not work as a full node right from downloading it. I thin you have to open some ports in order for other people to connect to your node. This information can however be outdated and best is to simply follow a manual on this.

I would recommend a mixer that is open source and reputable. If you can not check how the mixer is working you can definitely get scammed even if the mixing service is reputable. There are also a lot of "reputable" exchanges that suddenly closed and scammed a lot of people. So better to do some research and mix only small amounts from time to time.
To say that mixing services can not be shady is kind of shady in it self.

Maybe a 24 word seed phrase will however become more relevant in the future when there is more and more computing power available. Is there any calculation if it will be possible to crack 12 word seed phrases with a super computer maybe in the next 50-100 years if you take into consideration how fast the capacity grows?

Trading Shitcoin is just a gamble and you can win big or loose big. There is no possible way to control that and because of this reason it is nothing more then gambling. However if you look at all the crypto casinos you will see how many people are gambling addicts in this world. Even if Shitcoin trading is gambling it is probably not worse then casino gambling.

Is there a tool that can try to brute force the correct order of the 24 seed word seed phrase. I would love to give it a try, since it looks much more easy then it actually is.
There is really that weird thing with humans and probabilities that we are not really able to understand how unlikely stuff is.

Thank god we all have a free will and can choose to tell or not tell basically anything we like. I feel that it is false to tell people they are not allowed to tell how much coins they have. If you are happy to share what you have then it is your decision. Usually people do post like "I bough my first 50 USD worth of bitcoin" wich is nothing bad and will not hurt you at all.
Stilll it is not wise to make everything you do transparent.

So you thank him for believing in bitcoin in the same sentence where you tell him he can dump all his BTC in the next bullrun. This does not make sense at all, since you either believe in bitcoin as a payment system or you are here for the short term speculation.
Yes it is possible to believe in bitcoin and still trade it against fiat, but to accumulate and then sell everything ist just pure gambling.

I don’t really want any kind of refund on my cold card since I am still a happy user of my mk4. Still at the time when I bought it it was around 3x the price of the cheaper options that were available at that time (ledger, trezor)



As I said before this applies to any product with electronic components, if they need the update to work correctly. Usually a toaster would function happily for more than two years without an update. A smart toaster however could maybe need a security update to work correctly.
