Yes cryptocurrency is already another option of payment and it's spreading like wide fire.
Alot where initially critical about cryptocurrency some labeling it all sort of names like a ponzi scheme, fraud etc but it has actual caught there interest
But want thing I can say is that we might see this giant companies like the OP has just mentioned that accepts cryptocurrency or some that has not yet started following the same way as facebook and creating there own coin.
Should there be a limitation to this yes cryptocurrency has created an avenue for a whole new way of trading and transaction should any company just develop there coin just because they had already gained fame and altcoins that has been in cryptocurrency for a while would die out this would cause competition and might build of to an avalanche of coins in the future.
bitcoin and some good number of altcoin are my point of fancy in the cryptocurrency community. am not interested in Libra coin(still sceptical about it)
If this faint want to venture into cryptocurrency there should make use of the existing coins and not corrupting the whole system
Yes, cryptocurrency is already an alternative currency since we could already use it in some stores online and even in some physical store you could also use bitcoin as an alternative currency. But still the number of stores or even online that is accepting bitcoin was just so little so I guess we need a lot more time for the bitcoin to influence a lot of big companies to make them it an asset or a method of payment. I think bitcoin and some popular altcoins in the market is the only cryptocurrency that is going to be recognized by big companies as an asset since there are so many altcoins in the market that has no value at all.
There are already so many places where u can use cryptocurrencies as payment option therefore ofc where the soon is now.
Is some places you can only use cryptocurrencies. But due to not 100% of the population knowing what cryptocurrencies are they still have to make all other payment options available.
In the future i am sure something like this will happen as globaly and uniquely without fiat at all.
Even after a total fiat system collapse.
Agree bitcoin still needs a lot of time to completely influence a lot of places in the world also not all of the people are expose to technology like this bitcoin most of the time they are just aware of the traditional money.
Some of you people are putting the cart before the horse. The Lightning Network is still in its infancy and the scalability problem is not yet resolved. As soon as we have made progress such that the leading blockchains can handle thousands of transactions at a time, then, maybe then will we be able to talk about mass adoption.
