Thanks for your help.

Yes. Laptop 1 was once used to receive my bitcoin a couple of years ago. But since then has stayed offline. Has v21

Laptop 2 is connected to the internet but only for the purpose now of broadcasting my spending tx.
Will have V23 or can just keep v21.

I was just confused how to sign the offline tx on the airgapped laptop 1.

I was told that since I'm not technical and seem unable to understand the descriptor process or making a manual raw tx.

Then my only other way was to simply send (signed, where I type my wallet passphrase in) as normal with core unsynced on latop1 then close v21 down.

Copy then entire bitcoin folder over to laptop 2 which is connected to the internet and when it syncs up it will broadcast the tx
So although my keys will be on laptop 2 which is connected to the internet they are actually encrypted by my password that I dont need to enter because the tx was signed on the air gapped laptop 1 unsynced wallet.

The only problem with this easier way is that now the airgapped laptop can not sign any further tx in the future  until I update its blockchain to later date that the spend takes place. So in theory I will need to later copy the synced appdata file back from the internet connected laptop to the airgapped laptop.

I just wanted to check there are no big issues with this way.

I was thinking about sweeping to an electrum wallet and using the watch only psbt guide.
But if I can do this with core just have to copy over the appdata bitcoin folder and no programming with the bitcoin core console instructions. Then I'll stick with bitcoin core.

I'll work out the safest way to get the updated bitcoin folder back over to the airgapped machine in a few years when I may need to spend the last 0.005. I suppose this is the most risky part.

Thanks for the help. I see what you mean laptop 1 isnt a real cold wallet because it has been on the internet to receive the btc a couple of years ago.

If you think it's going to work I'll give it a try.

Edit. Also I'm not sure if I just need to copy the wallet.dat or the entire bitcoin folder over from airgapped to internet connected machine for the tx to be sent? 

Has anyone else used this method for a little bit of extra security over just sending straight from a hot wallet?

I suppose this just stops you from having to enter your password that encrypts your priv key on an internet connected machine.  So give some extra security.

Hi folks.

I'm wondering what to do.

I have an old core wallet.dat with bitcoin core v 21
This is stored on an old laptop that was only used to receive my bitcoin and been offline since.
There is under 0.1 btc which I know is a small amount compared with some.
I wanted to spend 0.05 without brining this laptop online.
I looked at an electrum watching wallet method but I was hoping I can do this with sticking to the core wallet.

I was thinking of going this route and wanted to know if it would actually work.

The offline  laptop actually uses an external drive plugged with usb to store bitcoin full chain (at the time of recieve), wallet.dat. So bitcoin core 21 installed to external ssd never used for anything else.

Now I could install core V23 and try these descriptor instructions but I feel I could mess that up and I would like to not add anything new to the offline laptop if possible.

Would this work since I know I've never made any other tx with this wallet?
Can I just spend 0.05 on the unsynced offline wallet only unlocking to sign on the offline wallet so only expose the password there?
Then shut core down  and then copy over this bitcoin appdata folder to a hot that can sync up and broadcast from the hot wallet?

I know that sounds like a lot of hassle, but I really I dont mind time consuming stuff rather than doing something more technical like using descriptors which I think I would get wrong.

To later spend the remaining 0.05 bitcoin then I would need to copy and updated bitcoin appdata file via usb to the offline wallet before trying to spend since the inputs and outputs will have changed ?

Is this a crude attempt to cold spend that would work the first time but for future spends opens up some strong vulnerabilities? With having to copy files to the offline machine.

Is a wallet.dat that is strongly encrypted with a 30+ character pass thought of as vulnerable? Especially if online for just a few seconds to broadcast? Then laptop shut down once again.

A lot of pos coins are constantly online to produce rewards ?
I just want to know is that reasonably safe?

I dont want to get a hardware wallet at this time because I've used core before and have not had an issue.

Are there any other ways with core to cold spend that are not pretty technical.
Someone tried to explain making a raw manual tx but it was confusing and actually I didnt understand it at all.

I was advised to use V23 on the internet connected wallet but just stick with V21 on the offline laptop and it should still work?
I appreciate a lot of people will think just send it over this amount but I do want to reduce the chances of getting hacked if possible.

If this very insecure I will just wait and try to learn another way.

Thank you for some advice.

Dont be fooled by the " teams" dot and atom are overrated. Blocknets tech is superior.
This was confirmed by several comparisons I have read. Ada is good but the ico was narrow.

Xby wallet is slow to sync who has some nodes to add?

I don't really like either at their cap.
Lots of projects out there that are capable of similar things or have almost identical usecases but for the real life changing opportunities you want small caps.

Blocknet and Bitbay are actually superior technically they are just unknown.

Where are the technical experts with the easy to digest graphical charts and comparisons.

I want potential 500x not 5x returns. I missed bitcoin in 2010.

You want solid robust tech microcaps that can do what these top 10 - 25 can do and better in some cases.

Japan only ico?
No thanks.

The main issue is there is too much centralized power on crypto in terms of marketing and duping investors.

I mean clearly Blocknet is technically as good if not clearly better than other similar projects at 300 or 500x the cap. Why?

Also Blocknet was out way before them.

I think coinmarketcap is the most dangerous site in crypto.
It totally is misunderstood by new investors.

They conflate high bogus and manipulated caps and volume with better tech and more successful projects.

There should be technical assessments made by impartial professionals that correctly assess the credibility and usefulness of the projects based entirely on merit.

Looks like a shady tactic to game coinmarketcap.

Chainlink is okay but after reading a few different articles BLOCKNET is as good if not better at the same thing.

Who would buy chainlink or atom who actually understood the tech and what it is capable of?

This entire market is mostly hype and marketing duping those without a clue.

Forget over priced over hyped manipulated schemes like chainlink and atom/cosmos and examine blocknetdx and xlitewallet.

Why pay 300x or 500x for the something that achieves the same thing or maybe actually not as efficient and elegant.

Hold a bit of each but clearly the best value here is Blocknet by a huge margin.

After reading about these 2 projects.

Why do copycats get supported by Binance or are they binance?


One has a market cap of 3 Billion?  ATOM / cosmos
One has a market cap of like 11 million  300 X LESS ?

Cosmos clearly looks inferior to Blocknet, what is binance doing here?
This video by well known chico crypto I have just seen looks quite worrying.

Blocknet looks to be a superior design and binance looks to me to be pushing inferior design whilst knowing that.

How can an inferior project be 300x the cap?
Who here can give further insight into this?

Hence you need a crypto with a built in decentralized market place and decentralized pegging solution that has an exchange or you can simply start selling items to acquire more coins.

There are such projects out there. Have a look around.

If you have a completely decentralized services and products marketplace built into your coin then fiat and banks for a lot of things become irrelevant.

Although if I lived in a country that pulled this crap I would try to move asap.

Looking at some comparisons between these coins with dex solutions. and discussing with various developers these projects are similar but most agree that Blocknet is technically as good if not better?

Who here has analysed these and why is Blocknets cap microscopic in comparison.
Let's have a fair and entirely open discussion and comparison.

Blocknet was the first to attempt an atomic swap dex or was there any that preceded that?
I would like to hear from any members who have investigated or invested in

Uniswap
Blocknet DX
Cosmos

Other similar projects.

Are there any developers that can give their thoughts?

I have a small portion of each of these now.  

Why does it often seem that the best design is overlooked and people essentially will pay 100x more for something inferior or no better?

Is it purely awareness?

All opinions are welcome but only discuss coins that offer similar functionality please.

Good list but a few problems.
Although I favour pow launches the initial distribution doesnt really define how decentralized the design is or how wide the distribution is after a period of time. Even pow launches are rigged and launched like steam or dash. Even if it's not proven it can be that the devs and a few friends mine up vast swathes.

The distribution though is impossible to determine correctly. Something that was very widely distributed initially can gravitate to a few huge whales undetected. What you require is whale protection so that even if this is the case a single whale can not manipulated the market. It is much more complex than it seems.  

For pure decentralized value in that they provide services in a decentralized manner that others cant compete with are

Blocknet - the best attempt at a dex
Bitbay - the best p2p market place, incorporating DDE and decentralized peg

Actually in terms of being truly decentralized nothing comes close to Bitbay.
The entire obsession of the developer ( among the smartest here) is to decentralize every aspect that could be decentralized.
Even the voting mechanism.

I have respect for many of the projects listed. Smooth is a great dev (aeon) and rat4( blackcoin now blacknet)
Monero of course.

However the stipulation of no ico is flawed. I prefer pow but the very best decentralized projects here that are not just copying bitcoin or Ltc but going further to fill the gaps of creating an entirely decentralized system with no need for centralized exchanges or services are Bitbay and Blocknet.

Other notable mentions are Zano, blacknet, 0byte, komodo, etc. These are some of the highest level developers here that are obsessed by decentralized everything.

Check out Bitbay. This has to be the very pinnacle of decentralization. They even have a dex on the way.
There is no project more decentralized.

Decentralized market place
DDE no centralized arbiters
The only real decentralized peg or anti volatility mechanism
Decentralized voting
Decentralized exchange almost done.
It is going to be its own decentralized entity that provides everything you could need to survive depending on no outside sources except the internet and the dev even has plans for this.

Yes there are 2 states of Bitbay. That is the elastic supply. Some are liquid and others are reserved or frozen.
The liquid supply is determined by both demand and the votes of liquid holders.
That is merely part of the genius.

I The only problem Bitbay has is that most investors in the crypto sector are unable to correctly appraise and analyse new projects.

There is no other project that can really be said to compare with Bitbay and certainly not outside of the top 25 on coinmarketcap.

Most of the top 100 if full of over priced and manipulated rubbish.

Some alts that are technically superior to many in the top 50

Go ahead and investigate.

1. Bitbay ( not the exchange)
2. Blacknet
3. Zano
4. Blocknet

The top 3 have perhaps the 3 smartest developers here along with teams from the very best of the top 100. I'm talking maybe 8 teams from the top 100.

Some very interesting designs many are unaware of. These are developers of outstanding talent. Most investors simply dont understand what to look for.

Blacknet

0byte

Nano

Zano

Bitbay ( not the exchange) interesting in numerous ways

Those points sound ground breaking.
The guaranteed withdrawal and only projects with real product are huge and advantages for investors.

You probably downloaded the standard QT wallet? Try the marketplace wallet this is the powerful one with all of the features.
Watch the instructional videos. Please comment only after spending the time to give it a fair trial.
You appear to have joined and immediately posted negative comments. Test and research what Bitbay is capable of.
Do you see that no member has provided another example of a project that can offer anything like this for the similar or even 10x its market cap.

This is a serious issue for solid projects with no hype machine behind them. They are looked over by new investors that are saturated with projects making grand claims that do not produce.  That is bad for crypto. A bunch of developers should congregate and form a project appraisal and analysis website.

Bitbay is clearly seriously under valued but getting the average investor to understand this is the current issue that Bitbay has.

Yeah I mean now the g7 are going to attempt to regulate strongly stable coins tethered to the dollar or hard assets in a centralized way then Bitbays dynamic liquid supply and volatility smoothing mechanism should be in a very strong position.

Do you feel looking at the sequence of past events that bay has been the victim of " bad luck" with exchanges collapsing or randomly giving you the boot?
You would have thought some large investment group would have seen the obvious opportunity here with this project. It appears to offer more than any other project I can find anywhere near this cap or outside of the top 25.

Do you feel most new investors are simply unable to locate strong projects alone? Hence why most end up investing in scams that simply vanish after a time.

There is no next ethereum as such. Ethereum is very powerful and has huge overheads.
There are efficient versions of Etherum that can provide a large number of the use cases ethereum can with much lower overhead.
I dont see any project improving on what ethereum seeks to do exactly.  They have the lead and the funding and network effect.
I see Bitbay ( the project not exchange) as the older but lite version of ethereum with other strengths that nobody knows or has caught on to yet.  Find it but don't expect to be able to buy it anywhere except OTC.

Others that will provide some competition may be ada, eos

Another one with vast potential but again totally unknown and impossible to buy is blacknet.
Still if you have limited funds and want to find the next eth, forget that and stick with bitcoin or eth.
