I'm not an economic analyst but here's my own opinion about this 
. It's up to you if you will agree or disagree on it hehe.
? What I think will happen here is that we will establish a new pricing standard (using btc of course) but I don't know how tho lol.
. It's up to you if you will agree or disagree on it hehe. 1. There is no question about Fiat money (whatever it is $, £ or euro.) thats its losing it's value, so the question is. If it got no value what value Bitcoin have then ? ( i will use bitcoin for must common crypto but thinking of any). Can't get my head over it.
I guess Bitcoin's price will rise. You know why? Because btc remain as the only existing currency so tendency the whole wide world will shift into it which result to a mass adoption. There would be a high demand for this asset therefore will result into a price hike. But well all of this won't happen either if from the very beginning mankind won't choose btc as their currency and prefer other means of transacting (eg. Barter trading). 2.If you imagine in let's say 20 years FIAT goes to CRYPTO all the way. You want to buy a car worth $5000 but paying in Crypto, how much would you pay ? if $ got no value.
Hmm, but how did you say the car was worth $5000 if $ has no value in the first place? You get my point ? What I think will happen here is that we will establish a new pricing standard (using btc of course) but I don't know how tho lol.
