> In response to new guidance from the Commodity Futures Trading Commission
Coinbase has always been trying to follow all the laws and show how "legal" crypto can be. If the CFTC says they don't like it then Coinbase is going to shut it down... maybe they'll try to fight it behind the scenes - but they want to stay online and making money.
If they were going to lie, there are a lot better ways to go about it than blaming a government regulatory agency which probably will be fairly open to saying "Yes, we did ask them to close their margin trades because XYZ"
Whatever their reasons, it's clear that it wasn't the CFTC's guidance that made them suddenly pull the plug.
I could kind of see them having conversations with a regulatory authority for a few months, trying to see if there's a way to keep having the product.
Then, when it's clearly "Nope, not going to happen", they shut it down. That could take ~6 months with extended negotiations.
As far as server load goes up, by how much does it need to increase to cause a problem? Are the numbers feasable, eg 100x volumes?
I still have trouble picturing how this conspiracy would work. I assume it involves coinbase pumping bitcoin prices with money that they don't have. They pump it all the way up, realize "oh shit we don't have enough real money to cover the fake money", and then pull the plug to stop the bleed? Can't they decide ahead of time how much money they can safely spend and stop accordingly? Why do they need to halt trading? If they stop pumping, and the price continues to rise, that doesn't cause them to lose any more money, because it's just other people trading with other people.

It's kind of hard to tell just by looking at the charts. Just because trade volume is low doesn't mean load on the order matching engine is low. If you spam the trading engine with tons of non-marketable orders, nothing will get executed (no volume), but the order matching engine will still have to wade through those orders.
Not saying that Coinbase does this, but incoming wires/ACH/whatever continue to roll in during an outage, but they can stop the initiation of any outgoing xfers, and then be slow with them claiming a backlog.
A big Canadian exchange, quadrigacx that blew up ~2 years ago was doing all sorts of tricks like this. Their bankruptcy is still ongoing, but somehow ~9 dollar in 10 went missing. The other 1 of 10 was frozen by a bank and eventually returned as $5m bank drafts that no bank would accept.
Kinda like "Your money is in Bill's house, and Fred's house", except Bill and Fred didn't have houses.
That would only make sense if coinbase was down for several days at a time. If it was only down for a few hours then that's nearly not enough time for enough money to flow in (aren't wire transfers batched per day rather than processed in real time?). It also doesn't answer my earlier question of "why don't they just stop pumping before they run out of money?".

Perhaps that's exactly what's happening at coinbase, but pointing to them being down when there's high trading volume isn't a convincing argument.
All depends how stuck they are.
Your confidence in coinbase, given they are unregulated in any meaningful way, is IMO misplaced.
I think you're reading too much into my comment. I wasn't trying to claim that cryptocurrency exchanges didn't engage in shady behavior, I was only claiming that the specific accusation of "they halted trading because of liquidity issues from their pumping" didn't make any sense.
You're saying you don't think that any existing exchanges are conspiring (or have conspired) to defraud?
> there have been multiple high profile stories of very large players engaged in fraud, embezzlement, and duplicitous price fixing, and they are completely unregulated.
Doesn't this make such theories more plausible, not less?
The outages aren't related to insufficient liquidity and only hurt Coinbase.
there isnt really a source necessary
nobody has any insight until they do
So how can they do this without getting caught (and they haven't been caught - firms like Alameda are watching closely)?
This sounds like one of those things that's easy to just exclaim but is lacking a mapping to anything specific
...Unless there's magically someone filling it just before they do (i.e. frontrun by an internal bot) every time they try. I have observed exchanges doing this. I don't believe that Coinbase is one of them, though, as others have pointed out with their positioning they are better of not to.

This quote from the above article, does not apply to crypto exchanges so far as I know:
"Rules govern how trading is done. Laws prohibit manipulative trading practices on both securities and futures exchanges."
