OK I bought some BTC at R24330 on luno and then the price dropped.
I have transferred this Airbitz wallet. I see there was a fee of like 0.0000002 BTC how is that recovered and who does that get paid to?

#78
Who can explain this: Luno says 1 BTC = R24100, Google and some other sites are saying 1 btc = R22000

Waits for @BitcoinZAR to shed some light.

I prefer to watch the Luno charts on this website: https://cryptowat.ch/bitx/btczar

You can set the chart to show 1m, 3m, 5m, 15m, 30m, 1hr, 2hr, 4hr, 6hr, 12hr, 1d, 3d, 1w depending on your preference

Luno has a fee of 0.0002 for a bitcoin deposit or withdrawal. At a price of 24330 per bitcoin, that transfer fee cost you R4.86 if I am not mistaken (24330 x 0.0002 = 4.86).

When you send bitcoin to someone, there is a transaction fee that gets included to include your transaction on the blockchain. Normally the fee is based on the size of the transaction in kb, not in $ value, so you could technically send bitcoin for $1milliion and pay the same as sending $10.

Luno have the fee included, and it adjusts depending on the current fee price for bitcoin, but they do not make profit from it, so you probably just paid the minimum amount to have your transaction included in a block.

Luno dont give you the option to set your own fees, but if you did, and set it as zero, your transaction would never be confirmed.

When you do a price check on Google, it simply takes the USD price, and then does a conversion on what that would be in Rand based on the current USD/ZAR exchange rate.

Google is not going to any S.A. exchanges to look for the buy / sell prices or latest trade price.

The bitcoin exchanges in S.A. dont price bitcoin on what the USD price is in Rand, it is based on supply and demand, like any market. So if there is very high demand for bitcoin locally, then the price will go up as traders will increase their prices.

Doing a Google search for the price is a little misleading, kind of like when you do a Google conversion for USD to Rand, and then expect to get that rate at a bank when you exchange your USD, which wont happen.

That $3000 price mark prediction for bitcoin seems very plausable now.

Thanks now I know cash doesn't have to left in the account to cover fees.

From the charts and reading I did I think ethereum will drop to about $65 and then it will start climbing ultimately surpassing bitcoin.

I read somewhere that one gets a VISA card linked to your Bitcoin account/wallet. Where can I get further details about this?

I found some info here for those interested. @BitcoinZar are you making use of this card?

There are a bunch of different suppliers of such cards....one of the biggest and most popular is Wirex/Ecoin, which is one of the ones I did a post on here: https://www.bitcoinzar.co.za/bitcoin-debit-card/
I dont actually have one of those cards yet though, as I was away, and unable to receive it in the post.

Another big company is Xapo.com, which is one of the more well known ones, and the xapo company itself is very well known in the bitcoin community.

I do have one that I have been testing from Coinsbank.com, which I think is awesome. I got it last year before I went traveling, and found it to be amazing.

I also did an advertorial post on Spectrocoin here: https://www.bitcoinzar.co.za/spectrocoin...ebit-card/ which is well known, but I have not actually tested the card they sent me yet.

It seems to me that most of these companies use the same card provider, so it probably does not really matter which one you use.

What I have found is that some of the cards do work differently though. All the cards are either VISA or MasterCard debit cards, but its the way they work with bitcoin differs.

Some of the cards are debit cards that are funded with bitcoin (Wirex / ecoin). That means that you deposit bitcoin, and the card is 'loaded' with USD / GBP / EUR, depending on what currency you have chosen when you signed up. When you fund the card with bitcoin, it uses the latest exchange rate to load the appropriate amount of USD / GBP / EUR onto the card. When you swipe the card here for Rand, it does the conversion and deducts the appropriate amount of currency from the card.

I prefer the other type of card that works differently, maybe this is the kind marco79 is talking about. The card I use is linked to a bitcoin wallet, so only at the time I swipe the card for say R100, is the exchange rate calculated, and the appropriate amount of bitcoin taken from the wallet, and converted to Rand. With this type of card, my balance stays in bitcoin the whole time, so when the price of bitcoin goes up or down, the amount of USD I can spend from my balance goes up and down too. I think this is also the way the Xapo.com card works too, but I still have to get one to test.

I have been using the coinsbank card linked to a bitcoin wallet for over a year now, and it works great for me. There are no fees for swiping the card, but if you try to withdraw cash at an ATM, the charges are high. I went all over S.E. Asia last year, using the bitcoin debit card most of the way because Standard bank shafted me shortly after I left the country. Even after pre-approving and double checking with the bank beforehand that nothing would go wrong, it was about a month and my credit card stopped working. I was unable to call from a mobile phone to S.A. to stay on hold and try to fix it, and the bitcoin debit card really saved me.

So if I had to recommend cards, I would say the coinsbank.com card is amazing, and I think Xapo.com is basically the same card under a different name, and probably also the spectrocoin card.

The wirex/ecoin card is different, and uses the other method as far as I know. What I have heard though is that they have a much better mobile app and better options / features, compared to the other providers.

What is nice about having a bitcoin debit card, is that if you are getting paid in bitcoin, you can use it to fund your debit card, and use the card to basically spend bitcoin anywhere in the world that accepts VISA / Mastercard. The vendor just gets Rand or whatever currency they use as normal, they dont even know its a bitcoin card. So its a great way to spend bitcoin, which helps if you earn bitcoin but dont want to exchange it to Rand, and withdraw it to a bank account to be able to spend it on everyday things.
