I have been trying, for a few weeks, to send Litecoin and Ethereum from my Coinbase wallet to an external wallet, but Coinbase won't allow me to do so. No matter how much I send, it always says:
"Amount is below the minimum (0.00100000 LTC) required to send on-blockchain."
and
"Amount is below the minimum (0.00100000 LTC) required to send on-blockchain."
The amount I have been trying to send is way more than that minimum, and I always have plenty left over to cover fees, but all Coinbase will let me do is buy and sell. I can't actually use it. For starters, it makes no sense to impose arbitrary limits, but isn't it a bit... well... scammy to lock people out of using their cryptocurrency? I can't even exchange it for Bitcoin (which will send without any problem) because they don't allow buying one coin with the funds of another coin (which makes no sense either) so if I want to send anything my only option is to sell the coin I just bought, pay them yet another fee, then buy Bitcoin, and pay them another fee still, just to be able to send what I should have been able to send.
Of course, we contacted Coinbase support, but no response to that in over a week. Similarly, my business partner has been trying to have our business account setup to use our business name since they've had all our business documented and FEIN and business checking account setup for multiple years, but every time we ask them about about fixing that they just ignore us. Last try contacting them was a month ago, with no response.
So without the ability to use a coin, and without any responsiveness from coinbase, what can we do? Unfortunately, we haven't been able to find any exchange to switch to that will do business in Illinois, so we usually combined Coinbase with Shapeshift. Didn't expect this type of problem though.
Here's a screenshot of the most recent attempt as proof, with address censored out.
