Thank you guys for your answers. Looks like I've got some reading to do.
I didn't know about the BIP39 passphrase, have to look into that.

I agree that investing in a casino bankroll is not exactly the safest investment. Your investment will depend on the gamblers and their luck on that platform.
Although not big, there is still a chance that you can lose all your funds if some whale get lucky and win big.
Take for example what happened to the yolodice investors a couple months ago.


As long as casino's risk is properly managed, this isn't really a problem, because a good casino owner would never create a situation where it's possible for the house to get ruined.

I'm investing in YOLOdice for 4 years now and got a total of 44% profit over this time. That recent drop is just small variance that happened in the past many times. Casinos can't guarantee you that there won't be short-term losses, but in exchange you can get higher returns than what other investing options can offer.

YOLOdice investors in LTC bankroll were racketed last year and I'm not sure if they've recovered yet. The loss of almost 80% of the funds isn't really "just a small variance".  Wink

Maybe I didn't explain well. I WANT to create a paper wallet (backup) with, for example, electrum on an offline computer and use generated address from it for long-term storage.
Yes, that is very possible. You can create a paper wallet and import the private key on electrum. Download electrum wallet from electrum.org, open the wallet, then click on Next> import Bitcoin addresses or private keys> paste or use the camara button to scan the QR code and press Next. Then, the wallet will be generated, but make sure you do it on offline device with no connection to the outside world. But, in this case, only that one private key and address will be used. The wallet will not be able to use new address(es).

But, why do you not just create an offline electrum wallet directly. All you need to do is to install electrum wallet on the airgapped/cold electrum device and should not connected to the internet, formatting the device before use will be the best for assurance that it is a cold wallet device. Then create a standard wallet and backup the seed phrase offline which will be accessible by you but safe from attackers. The wallet will be able to generate bech 32 addresses for you and also can be used to generate addresses to send Bitcoin to. The confirmation that you sent bitcoin to an address on the cold wallet can be tracked on blockchain explorer, or create a watch-only electrum wallet on another device for easy tracking.

Yes, I understand that part. But I would like to delete that wallet from the computer after generating the keys (address) and keep only the seed backup phrase. I wonder if there is a method to further protect a seed phrase from unauthorized use in case someone finds it.
For example, something like NeuroticFish suggested. But I'm not sure how secure the approach of inserting extra words would be and whether it would be easy to decode for a potential thief.
I've been thinking more about how to randomize word order or something like that.

Poz svima, ako sam off-topic ovdje slobodno mi recite.

Zanima me ako netko zna gdje je najbolje kupovati računalne komponente s kriptovalutama? Koji shop-ovi podržavaju to?

Ne moraju biti nužno naši u HR, bitno da dostavljaju i da su u EU zbog poreza...

Hvala Smiley

Od HR shopova ja znam za pcshop.hr (Magazin RS), futura-it.hr i uzishop.hr

Would it be possible to add an additional layer of protection to seed phrase paper wallet?
Paper wallet do not generate seed phrase, it generate private key and address.

what is the best and safest site to earn interest from my bitcoin?
Well, I suggest giving a try at those reputable gambling sites here, some of them offer investment to the bankroll but I will not recommend any.

I'm just throwing my thinking here so excuse me if the question is stupid.

Would it be possible to add an additional layer of protection to seed phrase paper wallet? Some kind of randomization so no one can read it without a magic word.
I know it's possible to use a one-way encryption with keyword, but I wonder if there's a way without using additional tools or services? I wouldn't want to use anything that could compromise security.

What do you think? Maybe someone has already developed some proven system?
3528  Economy / Gambling discussion / Re: Gambling strategies & tips from professional players on: February 06, 2021, 09:05:13 PM
Best way to gain loyalty or wager amounts? Microbetting on lowest payout and lowest house edge. Stretch that dollar, let those satoshis martingale themselves;) I'd go for easy 1 to 5% bankroll profit on tiny amounts. Then use those 1 to 5% as microbetting on lowest payout. When that's busted, rinse and repeat.

There you go, right there, good strategy from professional gambler!

Okay, maybe you're not a professional gambler, but the strategy still stands.  Maybe we can't beat the casino unless we are extremely lucky, but at least we can get everything we can out of it.
Loyalty programs can be pretty good at some of the casinos, especially rakeback bonuses. I mostly gamble on roobet and yolodice and both of them have rakeback.
3529  Other / Beginners & Help / Re: [General] Bitcoin Wallets - Which, what, why? on: February 06, 2021, 08:26:36 PM
If you were to store bitcoin and not use it, then I would've recommended a paper wallet, it's a way cheaper option. But since you're planning to spend from it on a regular basis, then as suggested better it would be better (security wise) to get a hardware wallet instead.


A paper wallet is also useful to protect your money from yourself if you want long-term hodling.
It's much harder to spend or gamble money recklessly if it isn't easily available to you. Smiley

3531  Economy / Speculation / Re: Bitcoin hits $40k on: February 06, 2021, 07:18:41 PM
No way in hell would I have thought it'd be possible to even hit $20k this year, seeing as how the economy took an enormous hit last year, but here we are.  I can't tell if this is a bubble or what's going to happen, but it sure is interesting to track.

Yes, no one can tell what's going to happen for sure. This doesn't look anything like 2017 so who knows where we're going to end up.
Although I'm typically not inclined to speculation, but as the days go by, $100k seems more and more likely.

There's nothing to do right now... but wait to see.

Plan je dočekati bear market s jedno 50% love u nekom stable coinu, 35 BTC i 15% ETH, ništa drugo ne čuvam.

Aha, ako sam dobro razumeo, nabaciti sto vise "sala" pre kripto zime. Shvatam.
3533  Local / Hrvatski (Croatian) / Re: Bitcoin TA (Analiza) on: February 05, 2021, 07:16:15 PM
Ako pogledate chartove altova u odnosu na BTC - imam osjećaj da altseason tek počinje Grin

Slažem se s ovime. Ja sam prvi put u životu potpuno van BTCa. Većina u ETH a ostatak po ostalim provjerenim altovima s velikim market capom.

Sad sam malo zabrinut. Smiley

Mislim da cu sacekati jos jedan napad na ATH sa BTC-om i videti hocemo li ga slomiti. Tek tada cu poceti da prodajem ili prenosim deo na neke altcoine. Nadam se da nisam pogresio sto nisam prodavao kada smo bili na 40 hiljada. ETH me malo iznenadio danas, ali sam ipak uspeo da prodam malo na 1750. Sada vidim malu korekciju pa ne znam da li da ponovo uletim ili ne. Wink

Dear sir
You are legendary member. But your information is not high quality just poor research. You are saying I have multiple accounts. You have written how many accounts do you own. These word are telling that your information are very poor and you are a third class researcher. Please mention my bitcointalk usernames that I have own on my redmi note 8
I like to see your search and challenging you if I have even a second account on my redmi note 8 then I will delete my account. I don't know who is the master of bitcointalk should takes action on you. Third class thinking Member like you really troubling newbie members giving them negative feedback


Oh, isn't that sweet? In addition to cheating in campaigns, you wanna get personal now? You deserve negative trust just because of your toxic approach.
If a third class thinking member has found your alt accounts and your cheating, what does that say about you?  Cheesy

If this rules not belong to bitcointalk then I don't think this rule is correct.

You violated the rules of the campaign in which you participated. What don't you understand?

Meni je baš to super. Svi smo sami odgovorni za lovu koju imamo. Izađeš van, naroljaš se i izgubiš novčanik - isto ti nitko ne vrati lovu.

Ionako ćemo svi kad kripto postane mainstream u toj mjeri da s njime plaćamo imati jedan glavni cold wallet čiji je seed zaključan i par walleta koji će imati lovu koju možemo i izgubiti bez da jako zapeče. Uostalom - i banke propadaju.

Istina, banke propadaju, ali onda imate osiguranja i bar neku vrstu drzavne zastite.

Pitam se da li vec postoje banke u kojima mozete da cuvate kriptovalute uz osiguranje od pljacke? To bi definitivno trebao biti custody novcanik.
Nisam proveravao, da li su sredstva na Coinbaseu osigurana?

Znam da ne treba ovo da se radi, al jbg, ali ima li ko da mi posalje 0.0001btc na 19EmeHZzQ8zXTz4L6fnMX3wLJj99J6yMbF ?  

Povecali min za ECD od kada sam ja poslednji put koristio a ovi sa CEX imaju retardirane minimume za withdraw.

Pa, to je po trenutnom tecaju oko 1,7 dolara? Naknade za transfer su visestruko vece.

Voleo bih da ti pomognem, ali ako moram da potrosim 15 dolara samo na troskove transakcije... hm...

U poslovnici 1 osoba može jednom dnevno sve skupa 15.000kn bez osobne.

Super znaci mogu 10 dana za redom ako zelim recimo 20k eura? Pa dobro, to je super.
Nadam se da nema nekih skrivenih caki iza toga, jer bi uskoro svatko tko ima 5-6ETH mogao posegnuti za ovim

Zato ja stalno plačem za poslovnicom u Rijeci. Lako vama u Zagrebu prošećete se kada god hoćete i dignete 15k kuna. Ja gledam onaj jedan jadni bankomat koji mi imamo koji u zadnja dva mjeseca nikada nije imao ni kune unutra kada sam pogledao. Zašto ga netko uopće postavi ako ga ne misli napuniti tu i tamo.

Osijek ili Vukovar/Vinkovci! Slavonija je opet zanemarena.
Ovde nemamo ni bitcoin bankomat ...


3538  Alternate cryptocurrencies / Speculation (Altcoins) / Re: Alt season start in 3...2...1 on: January 31, 2021, 08:03:31 PM

I do not understand the point of pumping the coins artificially and that too now when we are already in a bull market, secondly i was thinking that we got rid of pump and dump groups and market has matured a bit but now seeing this again proves me wrong.

Did you really need to quote the whole OP's post again for this comment?

Anyway, if you followed the news properly you would know that what happened with DOGE has nothing to do with pump and dump groups.

If I can hijack this topic for a moment (although my question is not off-topic).

What's the worst that can happen if the Electrum wallet ceases to exist in 5 or 10 years, e.g., the servers shut down and there are no new upgrades?
Will I always have access to my funds? Or is seed backup the only way out from such a scenario?
3540  Local / Hrvatski (Croatian) / Re: Jeste ikada razmisljali o mirovini? on: January 31, 2021, 07:44:28 PM
...

Ovo mi izgleda kao vrlo pozitivno razmišljanje. Ja ne razmisljam jos o mirovini, jer se nadam da imam dovoljno vremena pre toga.

Dozvolite mi da se samo osvrnem na deo u kojem navodite da u narednih 15 godina ulazete slobodno vreme da biste stekli dublja znanja o Bitcoinu i nacinima za zaradjivanje istog. Mislim da bi bilo uputno uz to odvojiti deo novca i ulagati u kripto, ma koliko on mali bio. Cak i 1 $ dnevno u kriptu moze biti vrlo vredno za 15 godina. A onda biste bili u mnogo boljoj poziciji da, uz steceno znanje i iskustvo, imate i dodatni prihod od toga.
