Most of these platforms are unknown, so it is best to avoid them, especially since many of Scam exchanges use new updated services such as the Lightning Network to convince others that they are feasible platforms.
The platforms may not be the right place for the lightning network because the main purpose of them is to make small and daily payments such as buying coffee, daily products and others +

From that list I only know bitfinex but it is still good to know there are others.
In a few years when Lightning gets adopted widely, the others won't be able to afford to ignore it anymore. Shits like coinbase will drag their feet to the last minute probably. I expect binance to be the second big LN exchange.
