In case of a fork, what should we do to receive the coins in Ledger nano S?
You're probably not going to be getting the coins from a shitcoin like this, as you're not going to want them plus the fact that you'd have to use your private key to get them. So unless you want to put your ENTIRE Bitcoin wallet on the line, then you're probably not going to do something like this for NEGLIGEABLE amounts of money.
I'd avoid all of these, and if everyone in the community did the same then people would stop.
