How can you get back your money with altcoin?  As soon as Bitcoin cannot be converted/traded to cash then automatically this altcoin will be in the same scenario as  bitcoin.  Nothing to do but move on, hold bitcoin forget about it and wait till it get to trade with cash again.  Of course participate in campaign  for bitcoin to be traded back to cash.

Cannot be traded for cash so you mean btc has no value. If that thing happen ill just keep my btc into my wallet until good thing happen again. Thats the best thing to do.

Why can't you just spend it instead?

You can spend btc at thousands of places worldwide.

maybe instead of creating another pointless topic with a hypothetical situation that will never come true, start looking around (even online) to find places to spend your bitcoin NOW, instead of waiting forever for the moon landing.

purse.io is a service which allows you to buy products from amazon at  discounted rates using bitcoins. the official thread link is here: https://bt.irlbtc.com/view/307922.0 maybe @op is talking about it. personally, i have heard many times about this site but have never tried to use it.

 lol. if bitcoin cannot be converted into fiat then obviously it will have no value in the real world usage, expect buying digital goods directly from online shops which accept btc payments, and donating something which has no value to a charity is just a waste of your time and the charity's time as well.

well if bitcoin cant be traded for cash maybe i am going to trade bitcoin for goods, or just simply jump to another alt coin that can be change to cash, unless all of the shop already implemented bitcoin payment so i dont need fiat to buy all my need, then i will stick to use bitcoin

I will trade my bitcoins for gold or silver.

Purse.io is a good idea as well.

I don`t think that this will happen.

This is hilarious... But anyway, I'll stop my journey if that happens.. Nothing is there  at the end...It's useless to collect it if it has no cash value or cannot be traded to real money, for sure many investors would stop their business from accepting bitcoin too since world will only accept money and not bitcoin anymore if that happens...

In short, we are doomed!!! Just kidding..  

Bitcoin is cash!Digital cash!
If you can not trade Bitcoin for fiat cash anymore, to me this means that fiat has failed.
So if somebody wants my Bitcoin, he will have to pay me in goods. For instance I give you 10 BTC and you give me your property.Or I give you 2 BTC and you give me your new car.
You see I'm looking at it from a different perspective.
