Dear users,
We are glad to announce that Lightning Network invoices for services are now supported on eXch!
It means we now accept non-zero amount invoices for LN.
The order's rate automatically converts to flat (1%) for them.
Kudos to you who keep improving the system for the benefit of your users.
What's going on here? I don't remember seeing Bitcoin reserves on exchanges barely above zero. Why is there so much demand for Bitcoin?
Also, it seems like the supply of XMR and LTC has never been higher
I just checked eXch website and I can see plenty of Bitcoin available, over 62 on mainnet and over 5 on Lightning, but this can quickly change.
Shortage of bitcoin is happening more often when Bitcoin price drops, traders are than trying to earn more money, and I don't see any issue with this.
I just noticed that similar amount of BTCLN was available in your screenshots, and this is a good alternative for several reasons.

The high demand for Bitcoin is due to the price correction and may be due to their need to sell Bitcoin to provide liquidity for DAI/USDC/USDT.
this is not the first time, as I have noticed several times that reserves have decreased to zero for some cryptocurrencies, including Bitcoin.

Almost every altcoin drops harder than Bitcoin, so I guess they're trying to limit their losses by exchanging for Bitcoin.
All the above explanations look reasonable to me, but I am very curious to know from @eXch Support about what is prominent when assessing exchange reserves in this case and to shed some light on the plumbing of flows they see.
