Il y a une FAQ sur le site de Ledger:
https://support.ledger.com/hc/en-us/articles/6314087134365-Ethereum-Merge-FAQ?support=true
It's completely safe to keep your ETH, NFTs and ERC20 tokens in your Ledger Ethereum account before, during and after the Merge.
On the day of the Merge, Ledger Live will pause Ethereum services (directly on the app and also through the Discover section) for as little time as possible, while making sure the network is stable and safe to use.
Though you'll still be able to access your Ledger Ethereum account via third-party services like Metamask, it's strongly recommended to avoid high-value transactions and NFT transfers during the Merge.
Important events like the Merge are magnets for scammers trying to gain access to your 24-word recovery phrase. Beware! You do NOT need to update/upgrade/sync/migrate your Ethereum accounts with your 24-word recovery phrase leading up to the Merge.
Il faut juste espérer qu'il n'y aura pas de bug. Cependant si il y a un problème ils trouveront une solution, étant donné les millions de personnes impactées dans le monde.
Et Vitalik n'a pas l'air d'être stupide.
Cependant... Le merge aura lieu le 15 je crois. Donc je pense que le 14, je vais encore échanger quelques eth (et aussi des stablecoins) contre de bons vieux btc.
