I guess that the first things you will need are knowledge to use 2-of-3 multisig wallets, some "trust" to get people start using your service and probably some advertising too.
Also keep in mind that there are quite some people on this forum that already do escrow and you may have to work quite a lot until you'll get to match their "trust" rating.

You're right. But I didn't like what they did afterwards, from trying to minimize what has happened, to various confusing e-mails to the customers, for example.
Your "the hack gone out of control" wording tells it perfectly. Many others got hacked and can get hacked, but I didn't really witness such a bad handling until now.


I didn't want to advertise, but .. here you are:
The best example for "today" is Binance. I got their card for free and the 1% default cashback covers the current 0.9% fee. The Fx rate is the Visa rate (or close). And one can use the exchange to convert to EUR/BUSD at market rate if he doesn't like, doesn't want, doesn't trust or feels like automated conversion from BTC doesn't work properly (for me it failed once and it worked 3 times, but I don't use the card that often).
The so expensive Wirex is in the process of replacing the old Contis cards with their own and they are also advertising that the fees will be waived. Of course, I want to get to see that, but I think that most of the fees will be waived because they have competition now.


People do spend. Always keep in mind that all the coins bought by some are spent by others. And the numbers show it's not only the miners.

Keep in mind that Electrum "discuss" with its own servers (or nodes), hence you'll probably have to also adapt ElectrumX (or electrum-server or similar) too and the project will no longer be so small.
Also in order for this to work, somebody will have to host those servers...
See https://github.com/spesmilo/electrumx


Nope, it has its server.


Probably ElectrumX will be a bit different too.


You'll probably have to distinguish between the networks and avoid LTC/DOGE signal themselves as BTC ElectrumX servers.



Although I am against BCash existence, this time it may prove itself helpful for you, since it has its own Electrum fork. https://github.com/Electron-Cash/Electron-Cash

Sorry, but you are late to the party. 
The same story is already discussed here: https://bitcointalk.org/index.php?topic=5314714

There are older Win PE versions that work without swap. On the other hand Win 10 backup USB is already 8GB required, so you'll need more. And for USB the price differences until 32Gb are small (then it starts doubling).
But... many voices are against Windows for mining. That's because of lower hash rate for some, automatic updates breaking configurations for others...
Why don't you just use a Linux? Especially since there are a few USB sticks especially designed for mining....

A hidden investment trust, under ToR, where you send your coins,... then what?
Not your keys, not your coins. For me it sounds extremely shady. I would be wary to send my coins to a new/not yet known company even if they make public info about themselves. If they are hidden, there's a very high chance you'll ... make them a donation.

Bitcoin can be stolen in many ways and I am almost sure that many of those people that have lost funds did so because they were clicked into phishing links and went to websites that look like blockchain.com

However, I don't know what do people expect from a website. The content of the page and possibly some other features too can be changed by anybody from the company and by anybody else powerful enough to trick your browser's DNS resolving (OK, lately with forced https this will no longer happen). This means that you are never to be sure what you run there.

If you look into their ToS, they're basically not liable for anything. And that's right, if one is lazy enough to use web services instead of a proper wallet then maybe he deserves his fate...

Since miners receive 13.7 million fresh new DOGE every day and since I don't expect the current hype last too long, my answer would be somewhere between 2 and 10 million DOGECOIN.
I had my days dreaming like you did, but then I've learned about the infinite supply.
Maybe I'm wrong.  Sometimes I wish to be wrong. However, don't rely on DOGE too heavily for buying as Cyber Truck...

Committing crime for Bitcoin is far from new. I'm surprised it still happens with Bitcoin since it gives a good chance to the agencies to track - sooner or later - those funds and seize them.
But since I'm not concerned about the well-being of the criminals, this is just fine.

More properly, iirc, the user cannot put there anything else than short plain text if he's newbie.
In time, with more and better posts, while ranking up, the signatures are getting allowed to get bigger, nicer, colored, with links, ...

Indeed, copper membership can allow some more for styling, but still not the "full package", from what it tells here:

I agree. They have proven that they have no idea how to properly handle users' sensitive information.
And since the competition starts coming out with cards one can use for kinda free, I see no reason to bother with whatever is Ledger going to offer.

People need a learning curve. As technology and as financial thing too. I myself got hooked to crypto because of DOGE and back then I was dreaming that it will grow to this or that value (like I see people asking now if/when it will reach 5$).
I got older and I've learned a lot since those days and now I know that its infinite supply makes it a poor investment. But unfortunately too many are now at the point I was in 2013-2014...

The man got a beer, got some sleep, then turned back. It was not BRB, so it was accurate 


Dogecoin's strength (and maybe weakness too) is its community. Back in 2014-ish, it could have been used for cheap and heavy advertising, at least. Although greatly diminished, Doge community still exists and could be used for mutual benefit. (Does Elon have such plans, who knows?)

With his infinite supply, Dogecoin is much closer to what we know and expect as a currency. Its 1 minute block time makes it more appropriate for payments than most proper blockchain-based coins.
It's not just a meme coin....


Maybe yes, maybe no. The problem imho is that people takes his tweets much too serious. Some are just desperate to find a meaning and follow him.

Testnet is great to learn to use the actual tools related to Bitcoin transactions, and for free (you can get easily enough coins for tests from testnet faucets). It may still be useful for you, but I can understand the idea of "earning" actual money too.
Just mining pools have certain (big) minimum amounts for withdrawal and you (and the students) may get disappointed big time...
Well, do some tests and you'll see for yourself. Maybe you'll have somewhat bigger chance with Dogecoin. I really hope you will...


SPV wallets are not hardware wallets. SPV wallets are "simple payment verification" wallets that don't require the download of the whole blockchain.
Hardware wallets are by far unnecessary for the scope of your experiment and indeed you can rule them out.


OK, point taken. But please consider teaching them also about HD wallets, seeds and change addresses


You'd be surprised. However, maybe you can find/print the paper wallets in a way they can be folded in 2 or 3 sides and the private key goes inside, hence the photo will only reveal addresses.

Since OP last logged in about one year ago, it may have been more useful to PM him in a hope that maybe the address linked to the forum is still active (and he has the appropriate settings).
Did @lonestar1 did that? Should we do that?!

There are places here and there offering lists with addresses that contain funds, so you can test for yourself.
However, this information doesn't mean absolutely anything, since some will keep all their funds in one address, while others will keep them spread in more wallets.

Imho it's not a good plan. The problem is that Bitcoin mining difficulty is very high and rising. That means that an old "unprofitable" ASIC will probably not get you almost any coins, or you'll need quite a number of generations of students to get to withdraw that dust.

If you want to teach students about mining, show them how mining works with any coin. You'll have to pick with every new generation a new worthless coin with low difficulty in order to show them everything, including hitting a block or at least receiving payout from the pool.

If you want to teach students about transferring Bitcoin, then imho your best bet is Bitcoin's testnet. This way they'll see the exact wallets they can use. And since Bitcoin Core needs very long initial sync and you'll probably want to have each student trying this on his computer, I think that a SPV wallet like Electrum would be more suitable, since it syncs fast and it can also work with testnet.

Paper wallets... they are kinda outdated if you want to show them in the "classic" way. Paper wallet is a nicely printed pair of private key + address. But nowadays it's easier and cleaner to introduced them to HD wallets and seed, which they can store instead of paper wallet, and with seed they'll have virtually infinite number of addresses, of which they can bookmark one or two and check on block explorers (there are also a few block explorers that can work with testnet too).

The other "104" list has 107 entries 
I've ran a diff between the two and for now these seem to be the 15 names you don't seem to have:

Dogecoin needs a proper SPV wallet for many years now. There was Multidoge in 2014, but now we are in 2021...
@dogemoon: your best bet would be to convince fellow Doges to get Electrum source code and modify it for Dogecoin network (or to make another SPV wallet). The problem is that also something like ElectrumX server is also needed for this (adapted and hosted), since that's the part that actually interacts with the blockchain.

This is incorrect. You need those coins only if you want bigger cashback.
Binance gains now many users for the card in Europe because it has basically no fees.
Wirex is also advertising some sort of no-fees card/account, but from what I know they're not there yet, but it'll happen rather soon. And then there may be some competition.
