I just checked all hardware wallets that can be purchased with Bitcoin or LN, and I got only 15 from 40 devices, no wonder that ledger is not accepting BTC
Imagine someone selling devices that should keep BTC safe in storage, but you won't accept that same BTC ... it just shows how much they support Bitcoin
You know what they say, verify don't trust. You should have checked the information you found on that site and looked on Ledger's shop yourself.
Ledger doesn't accept crypto directly, meaning from your wallet to theirs, but does accept it through payment providers like Crypto.com Pay and Bitpay. The quality of these services is another topic of discussion.
If you use crypto.com Pay, you can pay with BTC, CRO, DAI, ETH, USDC, and USDT.
If you use Bitpay, the accepted coins include BTC, BCH, DOGE, LTC, XRP, ETH, etc...
