Well... I guess that with every service there will always be people who will have problems.
Personally I never had an issue with Revolut. I'm holding about 1000€ there in XRP, hopping for the XRP price to go above 1€ and start using the card for buying stuff (like using XRP for the purchases).

I tend to trust companies on some level based on the experience I have with their customer support, and Revolut had a good support the few times I tried them. Not like "wow amazing support", but it was good.
Also good support I've found in Kraken and in Xch4nge who's ad I have in my signature.

What is going on with grin coin? I read some of the comments on here and they don't seem too bad, and the general cryptocurrency market is not doing bad right now but the grin coin price is down like 70% since it started trading on Poloniex.  Are they diluting, company selling coins on the market, or no buying interest? I bought some, bought more then bought more and all I did was lose Cry

https://docs.google.com/spreadsheets/d/1RO3zc5AvfN9rcVnrYnLjqCikFLHmD39_7MCV18lDrvc/edit#gid=0

I just read something very interesting in their Monetary Policy explanation!

"Currencies with set supply are extremely experimental. Miners likely need incentives to secure the chain beyond only fees. Note: currency deflation is historically not a good thing."

I had never asked the question before: What happens when if in a few years the mining rewards fall bellow a level which can support all the produced ASIC miners?
I guess many people might think that the Bitcoin's price will magically go higher in order to keep the mining profitable, just like many though the price couldn't go bellow 5000$ (or was it 4500$?) because mining would become unprofitable.
What will happen in about 1.5 years when the next halving takes place if Bitcoin's price is still around 4000$? Most likely half of the mining hardware will shut down. In that moment, there'll be enough dormant hardware to 51% attack Bitcoin itself. Scary stuff.

On that regard, GRIN is more balanced and future-proof safe.
Bitcoin's limited supply sounds good to investors, but there are some serious implications in the long term.

The thing is people who are into cryptos don't have the balls to hold it and they keep selling to big players who manipulate and cause pump and dump..
we have to wait for the real people until then keep hodl

I believe you're talking about ENJIN based on the posts above?
Before real people join a project like ENJIN, shouldn't the platform provide real products first? It's good that they're teaming up with Samsung but I'm sure they paid a lot for that marketing move.
Having a wallet that supports multiple coins pre-installed in a phone which is used in majority by non-crypto-investors is a reason for 500% pump? I don't think so.

45BTC "wall" on Poloniex @ 67330 sats. Cute.

Not sure if that "wall" you're talking about is a "ceiling" or a floor! Tongue
I'm trading in Bittrex and that price is slightly higher than where the market price is right now, so I guess it's a "ceiling" huh? Undecided

The teaseeeeeeeee ! haha


Everything you're always making looks amazing. I fully trust you that you'll deliver yet again.

Also, to provide a quick and non-technical version of your previous post (which I read just now),
  Double forgery happens when a delegate forges multiple blocks in their time slot creating multiple chains and this can happen either by accident or on purpose.
  The ARK team came up with a solution they call Proof of Double Forgery (PoDF) and it's a protocol that automatically detects, fixes and punishes the delegate who double forged.


A lot more technical details on their link above Smiley

Has anybody received payment for week four ?

Not yet and now that you mentioned it, I noticed that I'm missing 2nd week's payment as well.
I hadn't checked because I trust them, I only checked the spreadsheet and sow I was accounted.

I'll have to contact them I guess.

Is there a danger level where it goes too low to make asics worth bothering to develop? or is the asic plan just to use existing supported devices?


In 2019 I don't believe there's need for extensive R&D before a company like Obelisk can produce an ASIC.
Therefore the only cost we need to take into account is the production cost.
ASICs are largely affected by diminishing returns. What that means is that the more ASICs that are being put in use the lower their value gets (since the static block reward is split among more miners).

So if GRIN's price gets too low, all that needs to happen is for the manufacturer to produce only a certain amount of miners so that their users' ROI is a logical one.
Too many miners and they'll lose their customers' trust while their miners will keep being sold for lower and lower margins.

0.3 Eth converted to 51 CLM???
Oh also some BTC and LTC???

Could it be that 1 CLM = 1$?
Well I guess it will depend if the overall coin prices go higher or lower.

I don't remember many hack cases and how were they handled, but I think I know how it goes...
Whenever there's a hack on the top of the prices, the companies refund their users in cryptocoins.
Whenever there's a hack on the bottom of the prices, the companies refund their users in fiat based on the date of the hack.

I don't expect Cryptopia's case to be different.

HAIRCUTS FREE HAIRCUTS!
43.1986% LTC was lost in the January 2019 event.
14.0489% BTC was lost in the January 2019 event.

pays CLaiMs @ $27/ltc



BTC and LTC lost too? i thought only ETH and some tokens.

of course the "scam hack" will not be complete without the most valuable crypto-> BTC and a sprinkle of LTC on top  Grin
Any official announcement, where they mentioned they will refund stolen funds?

They have enough fund from "listing Fees" to refund users lost fund.    Cheesy

Seems like their official letter about the stolen coins is finally being sent to users.
They'll update users' accounts with "withdraws" that represent the amounts stolen and then "deposits" of something they call "Cryptopia Loss Marker(CLM)".
How this CLM will be used is unclear to me.

I just discovered this poll.

My position on that is cristal. All blockchains are basically advocating one thing in common, transparency. It should be the same here. Only way to be transparent is to keep the sheet public for everyone to see.

It adds another layer of governance (by forum users interested in it) and in the end it is just compilation of data that is already public.

You mean Grincoin is not a blockchain? Cheesy
I'm just joking, I understood your point and I'm of the same opinion.

When there's no real reason to not have the spreadsheets publicly available, the default should be to provide them. Even more so when hiding them can raise questions as to the credibility of the campaign.

Imagine a campaign which is supposingly running but in truth there are no participants. Yet the manager asks for people to apply and wear their signatures while waiting to be accepted. Then they delay to reply and they get free advertisement without ever accepting anyone!

Ripple has been quiet for some time and haven't responded very well to the recent jump of crypto, there might be a jump in XRP soon.

Ye... I've been thinking. XRP is very often moving indubitable of other altcoin and Bitcoin, I remember it was also the first one to start spiking back in December 2017.
Maybe if it's moving yet, it means there is no bullrun incoming yet, which should be good for investors but bad for traders.

My guess is that smart money is flowing into XRP when the market is about to shift and this the cause of this phenomenon.

I was a bit too busy on the weekend and I didn't follow the news... however judging by the last posts here and people's unhappiness, I guess there are still no updates as to when trading will be resumed?
Oh and nor anything official about if they'll share their damage with their clients or not I suppose.

bountyminer.io is not working anymore, no campaign tab is opening.
I've participated in your signature campaign for a month or more but I can't see any updated info on your bounty anywhere.

If you're still on it, then fine, but otherwise maybe we should lock this thread so that the bots-spammers can go home? I tried to read some of their comments but my eyes started to hurt.

675  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Ethereum: Welcome to the Beginning on: March 14, 2019, 01:00:14 PM
still looking for a decent ethereum wallet?
You should stick with Hardware Wallets like Tezor or Ledger to store your ETH, if you find other ETH wallets unsafe.

I too think there are not much of decent wallets for holding ETH and at the same time keeping the funds safe.



If you are specifically finding a online wallet to hold ETH, I would recommend using Blockchain wallet at the best as it already supports ETH.

show me a wallet i can load my json file into (apart from myetherwallet, or command line parity), i cant load erc20 tokens onto a trezor or ledger.

Wait, what? Ofcourse you can use your ERC20 tokens with Ledger! I know because I'm using one!
Ledger Live (the wallet's software suite) might not have a dedicated screen for the ERC20 tokens, but you can add any token in MetaMask and then link your Ledger with MetaMask.
It's totally safe because whatever transaction you request from MetaMask's interface will need to be internally signed from your hardware wallet, your private keys never leave your hardware by design.

You can also use MyEtherWallet with your Ledger, after MEW loads your wallet it'll find all (most?) of your tokens and if anything is missing you can add it manually using the token's address.
From reading your post, I understood that you though you can't connect Ledger to MyEtherWallet, sorry if I misunderstood something.

BCN/BTC market added.

It’s glad to hear that you have added BCN and BTC on your platform. Since so far, I am thinking of invest in Bytecoin (BCN), so can you please tell me the process of how to buy BCN from Crex24.com and what are the transaction fees?

I just wanted to add that I've used Crex24 before in order to trade XDNA and their process was fast and smooth.
I don't remember what kind of verification procedure they have, I think it wasn't extreme but I can't recall, however I remember that depositing and withdrawing was almost instant.

@amrulshare. That is why I said learn how to use the command line and know how to store your grins properly. Many people did not try when Monero was under $0.50, which might also have caused them to avoid buying it and miss an opportunity.

someone assumed , this protocol has a problem within cold storage in hardware wallets are tricky to implement. this means developing a hardware  wallet like  trezor or ledger is not possible ?

No way this is true. I don't know about Trezor but I'm a Ledger Nano S owner. Ledger offers 3 options of connecting to your wallet,
  • Through their own app, Ledger Live (obviously)
  • Through web apps, like MetaMask or MyEtherWallet
  • Through 3rd party local software, like ARK's wallet

I believe ARK's case is the best example. Ledger doesn't offer access to ARK coins from within their own platform (Ledger Live) like they do with most (all?) other of their coins.
Instead you have install the official ARK wallet and connect your hardware device, then your wallet(s) are automatically recognised and shown in the list.

Even if Ledger can't integrate GRIN in their platform, someone could create the Windows wallet so that it reads from hardware devices and accepts signatures from them.

The only real problem I can think of is if GRIN would require a lot of memory from the hardware wallet, is that what you meant with your post?
But even in that case, the newer devices have larger memory so it should be supported at least in these newer devices.

 Synchronization from the zero block of such a number of wallets is a really lengthy procedure.



yes but you dont have to wait for one to finish to start the next one ..  also most coins have boostrapfiles .

If your coin takes over 7 days to sync then either your on a 14k4 modem or its a dead coin.


But they need to sync their wallets only in order to be able to enable deposits and withdraws. They know the users' amount of coins and they have this amount already listed in our accounts, they could enable trading any time they'd want.
Ofcourse enabling trading but no withdrawing/depositing would have unknown side-effects, but just enabling withdraw/deposit by one coin at a time should be acceptable by most people.
How much would it take to sync both Bitcoin and Ethereum, one day? If Ethereum is synced then I suppose all ERC20 tokens are automatically sync'ed. Then prioritise the syncing of the rest of the chains by highest last known volume.

We Cryptopia's users are used to having their coin set in maintenance for weeks, experiencing the same "lock" after a hack wouldn't be a problem! Cheesy
679  Alternate cryptocurrencies / Speculation (Altcoins) / Re: Grin Observer - GRN/BTC - Price Movement and Discussion on: March 14, 2019, 10:36:32 AM
I would never expect me to say this but... "When ASICs?" Roll Eyes

My train of though is that, since ASICs are usually expensive and have a long ROI, whoever buys them is expecting the coin to have a great future, no one would invest in an expensive ASIC expecting to mine a coin for the 2-3 months of its hype time.
So if people believe in the coin, then they won't dump their mined coins.

This is why I believe that the introduction of ASICs will reduce the dumping by 30%-40%.
680  Economy / Scam Accusations / Re: HitBTC scam! on: March 14, 2019, 10:23:22 AM
HITBTC is scam!!!
For a whole month they have been asking for what cannot be confirmed in my country, and have been holding my money since December 20th. This is the worst exchange of all, do not place your deposits there, if you do not want to lose them. For me personally, this exchange does not want to return 0.8 btk. I sent them all the documents for verification, all confirming screenshots and so on. They are still asking me for some documents certified by the seal of a lawyer or someone else. In general, this exchange is just a scam.

I don't know your case, but when Chinese exchanges require documents that should not be necessary or are not available to your country, some times it's tempting to exercise your Photoshop skillz.
I'm not suggesting you to forge whatever they require though, this could make things even worse for you, especially if you have already submitted your real data.

My only advice is to just avoid Chinese exchanges, they can do whatever they want and you can't reach them legally.
