I want to create a simple website for my crypto-related startup project. I know the basics of HTML and CSS code, but I've never created a web site before. What I want is a simple but professional looking responsive design with simple navigation.
What do you guys think?
Should I hire a professional website designer for such a website?
What are some recommended website design tools?
Please note, my time spent on this project is not a problem, there are no deadlines.

Hello! the most important questions here is whether the website will offer user interaction. This means, HTML, CSS, Photoshop, Illustrator etc. are great in order to design the website, but, if you want transactions, databases, chatting, email support etc., then it's a whole other story.
Well... Here's the thing: why do you think people would set up ASIC miners in the cloud so you could make a profit? Why would they share their money with you if they had to do all the purchasing, maintaining,...
The answer to that question is: >99% of all cloudmining companys are scams, the <1% that's legit sells you 100% of their risk for a very small part of their profit... It's not a good deal either way IMHO. They (the <1% legit ones) just make you pay for everything and if they turn a profit you get a small share, but if the BTC price floors, the diff jumps up, their hardware breaks, their electricity rates jump up, you still pay for all those factors and get nothing in return.
In reality: if your electricity rate is to high to mine yourself, or if you don't have a suitable mining room or if you don't know how to setup an ASIC, i'd just recommend you not to mine. But that's just my personal opinion.

I thought that they could charge for the electricity + the storage of the ASIC miners, in exchange for sending you the mined BTC.
They could charge whatever they liked.
But I get your point and I realise that probably there are no such services...
Re: Safet - A wallet made in JAVA (WIP - Testing purposes only, so far)
I am currently learning Java. Please can you tell me how long its gonna take base on effort before I can generate wallet address with it and how can I learn everything about wallet
Hi, congrats! It took me approx. 12-15 hours. I work professionally as a java dev since 2018. I don't think that the java part is difficult. However, understanding the theory was a bit tricky. This website helped me a lot https://learnmeabitcoin.com/
Having private or lowkey life will make robbers away. Don't show anything on social media for just flexing because you're risking you wallet in that situation. Stop risking your identity for fame.
I have no social media! None at all! However, as I said before, I became obsessed with all that. I need some time off.
After all this time, I think Bitcoin has caused me more anxiety than fun and safety. I hate to say that, I start thinking oddly and insanely.
I will abstain from all that stuff. I will keep my wallets exactly as they are. I will not change anything at all! And I will stop thinking about it! If I can't stop thinking about it, I will have to leave Bitcoin behind and change my positions... Unfortunately!
I know many people will laugh, but it does affect my mental health... I don't know what went wrong... But something did go wrong in the process!

Re: Storing Bitcoin about 20 years and is offline paper wallet (Bitaddress) secure?
Everyone have contributed with their opinions here and so far, I believe every important thing has been said.
Two points:
1. Don't trust flash memory. It is not good for long-term storage. The most durable is the HDD. However, due to moving parts that exist in HDDs, you shouldn't put pressure on them.
2. If you generate 50 paper wallets, you will need to backup 50 private keys. It is doable, but not the best choice.
Why don't you do the following:
1. Buy an airgapped hardware wallet, like blockstream jade, seedsigner etc.
2. Create a wallet, totally offline.
3. Make 2 backups of the seed phrase.
4. Store the backups in different locations.
5. Generate an address.
6. Save the address on 2-3 places, so you don't need to open the wallet again.
7. Send BTC to this address.
8. Repeat step 7 as many times as you want.
In 20 years:
1. Turn on your device, if it still works. It should have the private keys in it. So you can do whatever you want.
2. If the device doesn't work, you can order a new device from the same company and recover the wallet.
3. If the company doesn't exist anymore, you can enter the seed phrase in any wallet you want and recover the funds.
Bonus point: You can create a watch-only address in your mobile device so you can see daily that everything is ok with your hardware wallet.

I love how Bitcoin makes me think... all day long!
I have to admit, that after all, I think the whole point is to try to find the sweet spot. But for everything you do, you will always find yourself a new problem to cope with.
1. You must split your coins in 2-3 wallets, to avoid losing all your coins if they are all in one wallet. But then you don't know what types of wallets to use.
2. You find what wallets to use. But then you must decide which wallet will hold the keys to the address with the majority of your money.
3. Then, you realise you must have backups for all your wallets. But how many backups and what types of backups.
4. You make the backups for each wallet. But then you must find where to store the backups.
5. You find a place to store the backups. But then you are not sure if the backups are safe.
...And I keep repeating all the steps, again and again...

In my opinion, you have created a good storage system for your bitcoins.
As far as I understand, you have three wallets, each of which has its own Seed - phrase?
If so, it seems appropriate to memorize these three Seed phrases. You can remember seed phrases using mnemonic techniques.
In particular, there is a popular mnemonic technique for remembering important information called Mind Halls. However, it is described in detail in the series about Sherlock Holmes.

Memorising 3 seed phrases is extremely difficult and is susceptible to errors. In my opinion nobody should trust their memory for long periods of time. Memory is good, but unfortunately, you can't manage what you remember.
The plan is great. Especially that you have kept two backups of the seedphrase so that just in case one of them goes missing or destroyed you have the other one to rescue. Also keeping 60% in a cold wallet which is not connected to any web is a great idea as well because the biggest chunk of your portfolio is then perfectly secure without any harm from hackers and even far away from you that you sell it in panic.
Thank you!!!
First layer wallet - 20%
Second layer - 30%
Third layer - 50%
This is what im doing similar to yours on which i do make out partition on my coins and this isnt only limited on Bitcoin but also
into other altcoins as well on which i do make out that kind of dividing so that i wont really be losing it all once i would be hacked or some exploit or do make out some mistakes.
It wont really be that hurting that much if ever there's some accident since we know that internet connected devices are really that always prone to these things.

In general, cryptography is a complicated subject. It makes you suspicious, not trusting anyone/anything. I love it for this reason.
The only thing that really makes me feel unsafe with paper backups, is the fact that the ink could fade after 20-30 years.
Yeah, paper backups can be a convenient and easy way to store important information, but their durability can be a concern. Based on my experience, prints from an inkjet printer can become unreadable much sooner than the estimated 20-30 years, and this can vary depending on environmental conditions. To mitigate these risks, it is a good idea to use archival-quality paper which are specifically designed to last longer and resist fading. Additionally, in general, laser printers and their toner-based output offer longer lasting prints compared to inkjet printers.
The problem is, I don't want to use a printer.
<snip>
2-3 years is still a decent time frame and you would be able to forsee any possible damage to the paper or visibility issues. Paper is more durable than most think and can last quite a long time if kept in a suitable location.My seed phrase is handwritten, in black ink, totally hidden from the sunlight, inside a deck card sleeve and inside a box, protected from moisture.
The most easiest way I have done this is via my ledger and one smart phone which is only turned on when I need to take out my bitcoin and spend them. So ledger everyone knows it as hardware wallet, you need the passkey and phrases and stuff. However, sometimes the security of your funds can be managed with simple tricks rather than getting too high techie about it! I have Mi phone which is old and I am no longer using it since 4-5 years now. Since then I have formatted it and only have mycellium wallet installed on it. Now the address is mostly used to fund it and I rarely withdraw anything from it. I have kept that phone turned off and locked up in my desk. I only take it out now and then when Mi releases any software's and mycelium updates etc. So far I am doing great, and it serves the purpose of security perfectly.
I guess this means that your mobile is not connected to the internet, is it ? I don't claim there is an issue here, I am only saying that this is actually a hot-wallet if it connects to the internet. However, I agree that your usage seems to be very safe, compared to someone's that would use their mobile for everyday tasks.
You would check up on your backed up seed phrases more frequently than a couple of decades and would identify any wear in the ink or paper before it becomes unreadable.
Well I have made a mistake... I can't check on one of my backups quite easily. Don't ask me why
I will however check once per 2-3 years to see if it's ok! Perhaps I will just make another copy of it no matter what the old paper's situation is. so the best is to go for the metallic sheet and got it encrypted
Hello! what exactly do you mean by that ?
Perhaps he was referring to stainless seed plate, you can read it here: Stainless steel Bitcoin Recovery Seed Plate.
Yeah, I think paper wallet is suffice, but as @Welsh mentioned you have consider several factors, might be good to have a safety storage box for your safekeeping in a bank if you can have that option as well.
Just remember though that it's not 100% guarantee, this kind of setup has it's drawback and you really have to prepare for the worst situation.
In addition to what has been said, OP i expect you to read through the lines and got the idea, i was referring to how you can get your seep phrase secured using a metallic sheet by getting your seeds encrypted on it, in case you're not still clear about the point we've both given you, this is another additional one to what Baofeng has given, https://bitcointalk.org/index.php?topic=5389446.msg59506339#msg59506339 it's all about how you can secure your seed phrase with washers.
Brilliant idea! I will definetely do it this way
Paper wallets can suffice, but it entirely depends on your threat model. If you're concerned about them getting damaged or destroyed via fire, water or anything that could potentially come in contact with them, a metal wallet tends to have higher security based on that. However, the major concern would probably be physical security such as theft. If it's safe from theft, then the other outcomes are relatively low.
However, this depends on your current arrangement, and whether you're storing them in a house that's prone to flooding or has old questionable electrics. Only you can really determine that, otherwise you risk compromising your security. If you're storing your paper wallets outside of your house, then look at the environment you're storing them in, and decide from there.

- Non-circulating BTC: ~60% of my BTC in a cold storage air gapped device
What is your air-gapped device's setup? Because mostly, hardware wallets are enough, and that definitely not everyone is capable of properly creating a proper air-gapped device.
Well I have my keys in Blockstream Jade and I only use it to sign transactions using QR codes. I basically do this: https://help.blockstream.com/hc/en-us/articles/11664909888537-How-do-I-use-Jade-QR-Scan-with-BlueWallet-
Hello! Bitcoin is a big part of my life, in both qualitative and quantitative terms.
I have been struggling with identifying how I should organise my Bitcoin. I guess we are all familiar with organising our FIAT money in several bank accounts etc.
I currently have:
I use my second layer wallet when I need to fund my first layer wallet, which I use for payments. I plan to leave my non-circulating BTC to my children or perhaps I will use some of it once I am retired.
I have dual backups for my wallets, stored in different places.
I want your opinion on the following:
1. What do you think about my plan in general?
2. I currently have paper backups and I plan to change my backups from paper to metal, especially for my hardware wallets. Do you agree with that?
3. Would you want to share what you do and how you organise your Bitcoin? In fact, I might be able to get some ideas from clever people in here! So please, shoot me with your thoughts!

Thanks guys! No luck so far
At some point it becomes far too obsessive and you want to try too many crazy ideas, so I'm just trying to slow down a little and not get too excited to keep my sanity, haha

Hello! Let tell you my insane ideas, just in case
1. your birth date
2. the phrase "THE DATE"
I wouldn't try to find a bitcoin specific date, but I would rather start searching for an important date for you or your father.
Forgive my ignorance, but if the address (Satoshi's genesis address) contains the unspendable BTC, does is mean other Bitcoins that get there become unspendable as well? Of course, these coins aren't likely to ever be accessed anyway, but, assuming Satoshi is alive and didn't lose access to anything, would Satoshi even be able to use those coins? pooya87 says it's possible, which gives some hope these coins aren't just burned.
IMO, if one has such money to spare, it would be better to donate it to a good cause instead of burning. I don't think it was done by mistake, though.

Well, let's clarify something. It doesn't matter if it's Satoshi or if it's me (let's say), but anyone who have the private key that unlocks the genesis block address, can spend the money found in it.
Therefore, if you decide to send BTC there, the only way to be spent, is if someone has the key to this address.
If Satoshi is a person and if Satoshi is alive and if Satoshi owns the key, then they could definetely spend the BTC you send there.
Thus, it's definetely not verified that this amount of BTC is burnt.
If you want to "burn" some bitcoin you can generate an address, send the money there and ELIMINATE the private key that has access to it.
