Two things:
1. Bitcoin Lightning is not Bitcoin and is in fact a centralized by design layer 2 system which the transactions are off-chain [0][1], a direct contradiction to what Bitcoin was designed for. A peer-to-peer on-chain electronic cash system.
2. Monero and the other privacy coins are getting delisted and banned from exchanges due to increasing regulations. [2][3][4]
You can still use Monero, but the on-ramps, exchanges will have banned the privacy coins under these regulations, cutting a way to easily exchange it for fiat.
