Ran into the same problem today 1/18/21. Contacted ETHOS support and was informed that phoenixminer 5.1c had this bug.
Since phoenixminer is not native to ETHOS, the regular miner update command does not work.
Suggested to use...
bash <(curl -s https://raw.githubusercontent.com/cynixx3/third-party-miner-installer-for-ethos/master/miner-manager) phoenixminer update
This updated to phoenixminer 5.4c and the problem was fixed.

Update on searching for a Coinbase alternative in the US.
Short answer, Coinbase is still the best option.

Coinbase has very high ACH limits and limit buys of only 0.15% if you wait 1 week before buying on Coinbase Pro.
Gemini starts with ACH limit of only $500 per day than goes to $1000 per day. Buy fee is 1%.
Kracken does not accept ACH so wire +fee is the only option.
Cash app appears to be 1.2% above spot.

Please keep this thread updated if you find better fee structure than Coinbase on both ACH and fees.

Hello Bitcoin Forum.

Can anyone suggest a good alternative to Coinbase?
I personally don't have much respect for the company with their recent actions and many failed wire-transfers in the past.

The reasons I use Coinbase are...

1. Instant bank USD -> Coinbase USD wallet and I can make a BTC purchase right away (unfortunately paying their high fee).
2. I can use limit orders to purchase/sell BTC without a fee
3. Trying to get my folks into crypto, so I like their simple interface to buy/sell crypto for those not using Coinbase Pro.

Are there any other exchanges that I can use that have these features?

TY!

Hello Diamond community.

I’m hoping to partake in the PoS part of keeping the network secure.
What is the number of DMD coins that I need to make it worth while? What should be my expected ‘dividend’?

Two things I’m hoping I can get assistance on.
How do I get a DMD wallet up and running on Ubuntu (17.04)?
How do I import my existing wallet address?
How do I setup the wallet to run as a deamon on Ubuntu for staking so that it comes on automatically when my machine boots up.

I’m no Unix expert, so if you have very simple/outlined steps, that would be greatly appreciated.

Looking forward to being part of the DMD community.
