I couldn't find my ledger nano until about 20 min ago and 90% of my holdings were in altcoins... Is there anything I can do?
I assume not, but figured if I was going to ask, I'd ask here
You will not get any Bitcoin Cash because you did not hold BTC when the split happened even though you have a private keys or no you still can not claim it.
Bitcoin Cash created based on our Bitcoin,it's total Clone how much you have Bitcoin in your pocket = Bitcoin Cash you will get.
the only way to earn it is buying that thing on exchanger.
you can go to Bitfinex,Bittrex and other exchanger
although you missed it,i think with your action buying an altcoin it's a wise move by the way.
you will profiting from it,so nothing to lose for you.
