I didn't follow this thread so not sure whether they already announced about this issue.
BitSler support

The support team has confirmed that they disabled currency exchange feature because it is a gambling site, not an exchange site. It is disabled until the crypto market stabilizes but not sure when it happens. I didn't find any info on this thread so just posted for you guys reference.
Why don't they just charge a huge % fee for the currency exchange. That way it would be very useful for the small transactions and people with large balances would just withdraw the BTC.
Really with more and more exchanges and services used Segwit already to keep these transaction fees down because this is getting crazy.
Also I hope that in a year or 2, more and more services will run on LN.
