ok it is not may be but the "converted" are preaching it that way! I have no doubts about the technology it is based upon it's usefulness, or the coins as a trading ( not investing) instrument.
To a traveler yes it would be great to deal with same currency around the globe.. in other words like Euro where individual currencies were abolished and replaced with a universal currency , now add that to the technology crypto is based on = a global decentralized currency but if it is not backed by any assets a reputable regime how does it store Value?
in layman terms USD is backed by the assets and whatever power US govt has, so is say Singapore Dollar etc etc...
also it raises these questions ( example my small business)
- why should I take on currency risk by accepting payment in Crypto?
- supporters of the currency ( not the technology) say there is critical mass behind it and in my example I should have no problems in converting the crypto balance to $ but that critical mass can disappear tomorrow !
- Multi crypto , if we are going to create multiple Crypto currencies then is it not same as having USD?AUD?GBP?EURO etc
Your other point about "you don't necessarily have to be exposed to the volatility "
How? if I hold Bitcoin as an asset every second it is marked to market! and looking at the volatility I wonder unless I am trader why would I bother?
You're asking basic questions about bitcoin (cryptos) as if you only learned about it yesterday. Bitcoin was started 9 years ago and it stared with no value to where it is now. There are many resources available for you to study if you are willing to learn. Some of them are posted at the beginning of this thread.
As I mentioned, if your business were signed up with a crypto payment processor (such as Bitpay or CoinBase or CoinPayment), they will accept the crypto payment on your behalf and immediately convert to fiat for you. NewEgg is signed up with BitPay, for example, and CheapAir.com is signed up with CoinBase as another example.
