  • Basic help needed | 2021-03-02
    You can either keep trying to withdraw until the fees are low (it shows what the fee is before you submit the withdraw), or you can use a mempool tracker to view current conditions. I like , very easy to understand
  • Sent BTC to CoinEX from CashApp. Still not showing up after 24 hours. | 2021-03-02
    Check your transaction hash here

  • How can I bump up my transaction fees? | 2021-03-02
    Please, check on this site paste your Transaction id and search it. Check if RBF flag is green (means ok), and can you paste here the fee in btc amount? No way that with 88$ it is still unconfirmed. With like 15$ o 20$ you are #1 in the list.
  • STUCK TRANSACTION | 2021-03-02
    Right now, anything under 7.1 sats per byte is purged.
  • Withdrawing | 2021-03-02
    I like to use but it’s not the only one
  • Earning Interest | 2021-03-02
    And when you'll have your own wallet, if you have to move your coins, make sure you check and learn how to use it to select the right fees to not overpay fees and the right time (often weekends are less congested so cheaper fees). But for now, what matters is how much Coinbase charge. | 2021-03-02
    You might also spend more on transaction fees than you would earn on rewards. no matter what you do with your coins, make sure you're smart about moving them around (i.e. as little as possible, during times of less mempool congestion such as weekends, using Bech32 addresses with RBF, watching to not overpay fees, being patient etc)
  • Miner fee alert | 2021-03-01
  • Can i mine to another wallet through nicehash? | 2021-03-01
    I usually use but you can also just keep trying withdrawals on NiceHash and it’ll tell you the price of the transaction before you submit it. Once it’s down to a few you’re comfortable with (I aim for 0.1%, so 6¢ on $60, for example) then you can go ahead and submit the withdraw request.
  • Transaction delays | 2021-03-01
    Look up your transaction here and see what fee you paid versus what is being processed. My guess is that your fee was low.
  • BTC deposit is still pending.... | 2021-03-01
    You can then use to look up if the transaction has been confirmed or not.
