It wasn't instant when I used it a few years ago. Worked only during office hours in Panama, and even then not instantly.

The good news are that my friend kept sending emails to Coinapult support, and they finally gave him his $$ back.

It was still strange, because he suddenly had a second Coinapult account in Mycelium, where the money was.

The system is obviously broken, and I can no longer recommend Coinapult. It would be very nice, if it worked speedily and reliably, but it didn't in this case. Instead it showed an indication that the system is defective.

Has anybody here recently used Coinapult in Mycelium? I had used it successfully some time ago, but a friend of mine recently transferred bitcoins, but got nothing. The bitcoins just disappeared, no dollars appeared. He waited a week---nothing.

On Sunday he wrote them an email and got a friendly, but automatic email back, stating that they would reply again within 24 hours, which they haven't done. I am waiting for his next information.

It would be helpful to know whether Coinapult has worked well for others or whether there have been similar problems already.

The relevant standard for the seed backup words, over and above BIP39, is BIP44.

Wallets that are BIP44-conformant should properly recognize each other's seed backups.

Coinomi works for me, but I would still recommend to retry Mycelium. Perhaps tapping the sync button, the two circling arrows, helps. Mycelium works well for me also.

Mycelium is hard to beat.

I don't need bcash in Mycelium. I installed Coinomi to move bcash out, and after that it's not needed any more.

On Reddit some people post essentially that Mycelium is dead. That would be a pity. Mycelium is still the best Android wallet far and wide, and the Mycelium Marketplace has no equal, certainly not in Germany, where it replaces Localbitcoins.

I think it is time for the Mycelium developers to raise their voice and tell us what's happening.

The spy organizations would have a field day if every bitcoin user combined all their holdings into one address. That is exactly what the invention of the HD wallet aimed at preventing.

The result is that all addresses of every involved HD wallet would be associated, for everybody to see in the BCH blockchain. Since these are the same addresses and the same amounts as in the bitcoin blockchain, this residual bit of privacy would be gone.

Prescient, if not clairvoyant. 1 and 2 are now almost certain. We will see about 3.

You did not foresee that the exchanges would refuse to receive BCH, but this is only amplifying your prediction and making the effect even worse.

There is a risk for BCH that hash power will be so minimal that it becomes too fragile to survive even into phase 3. After all, who pays the miners to mine something that does not yield any noticeable reward?

I personally would prefer to see BCH survive at least through the rest of the year to make it obvious to everybody how a hostile bitcoin hard fork without large majority support fares. I never believed that it could survive in the long run.

Thanks for the good answers! I think I understand the problem a bit better now.

In a normal HD wallet, after normal use, does each address not have exactly one UTXO?

When I send from an HD address, how does Mycelium select which addresses to send from?

Actually I would like to know whether I can influence which address is used by choosing a particular amount to transmit. For example, if I choose to send the exact amount of one of my addresses, will Mycelium then empty that address? How about the fee in this scenario? This would amount to some kind of indirect coin control. Would be nice to have.

Currently my biggest fear. People here will argue that it is, economically judged, not inflation, but what the average person (and the journalist and the government and the bank) sees is that there are suddenly up to 42 million bitcoin, rather than 21 million.

And that is not the end of it. Once we have proved that cryptocurrencies do actually split, then who is to say when the next split will happen or when the next cryptocurrency will split?

This could be the end of the cryptocurrency experiment. Enjoy it while it lasts.

A theory adequate for today requires us to think for ourselves, standing on the shoulders of giants of the past, not kneeling in front of them.

Last I looked the required fees for an on-chain transaction were below 5 satoshi/byte. Those seven weeks of transaction spamming are over. Bitcoin is as usable as ever, apart from the fact that it is also as slow as ever with an average of one block every 10 minutes.

This slowness would break its back, so Segregated Witness ("SegWit") was developed to double the block capacity and to enable fast, cheap, anonymous, trustless off-chain transactions. At least two of the new systems are currently being developed and tested, the Lighnting Network and TumbleBit.

Things are going according to plan. I'm not sure what you are talking about.

A new bitcoin that cannot do fast transactions? Wait until the person next to you pays for his coffee in a second through the Lightning Network while you are waiting for 10 min or an hour for your confirmation.

Economists do not determine the future of bitcoin. Ordinary users do. And they don't understand any fine economic points. They only see 42 million coins instead of the promised 21 million.

Journalists will also have a field day. You know how precisely and honestly they report.

The bitcoin price has always tanked whenever there was a threat of a hostile hard fork. We may end up with two worthless cryptocurrencies.

The Trust Attack – From February, but as topical as ever.

TL;DR: Governments and banks would have a field day. They would say, see, they have inflation. They always preached that there would never be more than 21 million bitcoin. Now there are 42 million. This is the perfect wedge to drive into bitcoin and discourage all users.

When a Mycelium HD wallet generates hundreds of addresses, is that a good reason to create a new one from scratch, i.e. a completely separate new HD wallet?

Or does an HD wallet easily work with, say, a thousand addresses? How about performance?

Thanks for your reply! I see that one of my old, non-HD wallets in Mycelium bears the green label, "(Local Trader account key)". That must be it then.

I deleted that wallet, but the Mycelium Marketplace still kept my Local Trader identity.

Then I found a function to delete my Local Trader identity and used that. And this was the solution. My trader identy was deleted, and I could create a new one while keeping everything that is unrelated to the Mycelium Marketplace unchanged.

What is the easiest way to change your Mycelium Marketplace name?

I suspect the only way is to create an entirely new identity by erasing Mycelium (after sending all bitcoins elsewhere or by using a second smartphone) and starting from scratch.

But please let me know whether there is a more convenient way.

Mycelium's automatic fees are getting ridiculous. Mycelium sets a "Low-prio" fee that is 10 times higher than the lowest-fee transactions that were being cleared during the last several days.

For example, until today the required fees for confirmation within a day are a tad above 20 satoshi/byte, yet Mycelium lets us choose no less than 235 satoshi/byte. For at least three days all transactions with fees above some 40 satoshi/byte have been confirmed.

This is stupid. If they cannot predict the fees, they should at least allow users to set their own fees. I have a lot of understanding for trying to make the wallet idiot-proof, but this is going too far.

It is also unintelligible why a wallet should not be able to see clearly the lowest fees that were successful during the last couple of days and allow the user to set a risky fee a bit above those. There are transactions, particularly those with a low value, that need a low fee, but that are neither urgent nor important, i.e. the user wants to take the risk that the transaction does not get confirmed.

Does anybody know an Android HD wallet that allows me to set the fee?
