It depends on luck as well.
Even if you pay a very high fee, you may have to wait hours for the next block to be found.

The next block may be found in a few seconds, or it may not be found even after an hour.

Not all nodes validate transactions.
Transactions are validated only by full nodes.

Just a small correction:
Transactions are not confirmed by nodes. They are confirmed by miners. Nodes only verify blocks.

If you are in hurry, you don't really need to wait for Mycelium developers to fix the problem. Mycelium is a non-custodial wallet and gives you the Mnemonic phrase (a list of 12 words).
For exporting your Mnemonic phrase, tap on "Create Backup" at top of the screen.
You can import the Mnemonic phrase into other wallets like myetherwallet.

Warning:
- Importing the seed on an online computer can be risky. It's more safe to do this offline. (Click here to read the guide.)
- Import your seed into myetherwallet only if you understand what you are doing.

What's happening?  Is the smart contract compromised?
The total supply is increasing insanely.
The total supply should be 19,200. Even the supply shown by etherscan is 19,200.

Take a look at the balance of the address below.
0xedffb62e23b9b7933f1684441007cda232d3bd8f
It is holding more than 440 ​million tokens.

You can do it on your own.
If you know your BTC address, just enter it into a block explorer like blockchair.com
If you don't know your address, you first need to click on "Window" and select "Receiving addresses" to see all your addresses.

No, Reward points price depends on BTC value and I remember days they were worth more than 1 satoshi.


Given the current value of bitcoin, each reward point should be now worth around 0.14 satoshi.
Since there are only 8 decimal places for 1 BTC, they are giving 1 satoshi for every reward point. They may add 9th decimal place in future and decrease the RP price.

Each reward point is worth 1 satoshi.

It's possible to generate addresses beyond the gap limit.
If you click on "New address" more than 20 times, electrum will generate addresses beyond the gap limit.
Addresses generated beyond the gap limit are highlighted in red and electrum displays a warning saying that the address cannot be recovered automatically if you restore the wallet from seed.

They have not been removed.
You should select the graph you want to see from options shown at top of the page.




Same issue. Currently, I see a blank page too.


I recommend you to use bitcoindata.science.
The tool has been made by bitmover and below is the thread.

UPDATED - Plot your transaction in the mempool

Coinomi gives you the seed phrase and you have control over your fund.
The problem is that coinbase is closed source and we don't know if our seed phrase is stored in their server or not. There is no guarantee that you are the only one who has access to private keys.

All addresses shown in "Addresses" tab are yours. They are all backed by your seed phrase and can be used for receiving bitcoin.

Note that addresses highlighted in yellow are your change addresses. This means that electrum will use them for receiving the remaining balance of selected UTXOs whenever you make a transaction. This doesn't mean you can't use them for receiving bitcoin.


In the case you are referring to Electron Cash, that's not a bitcoin wallet. That's BCH wallet.

Both Mycelium and Coinbase wallets (the non-custodial coinbase wallet, not the custodial one) give you full control over your coins. In both of wallets, you can export your seed phrase and recover your fund in the case they are not available for any reason.

The post was edited to add information about coinbase wallet.  
Thanks Charles-Tim for clarification.

Go to "Premium" tab and click on "Transaction history".
That's under "Your current benefits" table.

Not all closed source wallets get extra fee for transactions.
For example, Exodus and Trust Wallet both are closed source. But you don't pay any fee other than miners fee.

Have you checked the balance of the address?
To do so, you can enter the address in a block explorer like blockchair.com.

You are probably referring to Kingdice.
The website is down since September 1, 2019 and there hasn't been any update in the past months.

The 1000 satoshi is the bonus freebitco gives to the users who become active after a long time of inactivity.
You have probably received an email regarding the bonus.
Read the post below made by TheQuin.

According to Armory FAQ, the default location for wallets on OS X is

You don't see any address, because listaddressgroupings only shows used addresses.
Also, your wallet is not synced. Even if an address has been used, bitcoin core is not aware of that.

Use the command below to see all your addresses (used and unused ones).


Note that, you can see list of all your generated addresses using the GUI too.
To do so, click on "Window" and then select "Receiving addresses".

Just a small correction:
Using native segwit addresses, the transaction fee can be decreased even by more than 42%.

The transaction fee is decreased by 26% when there are 1 P2SH input and 2 outputs.
The transaction fee is decreased by 42% when there are 1 bech32 input and 1 output.

For example, size of a transaction including 10 bech32 inputs and 1 output would be about 722 vbytes and 1524 bytes. That's more than 52% reduce in transaction fee.


P.S.
Credit for the calculations goes to bitmover. I used bitcoindata.science.
