I don't think that bitcoin is the future of money, for that it has too many weak spots.
But I think that the future of money will be digital.
And I think that somehow a blockchain will be involved, since it has proven to be very useful in terms of bitcoin.
If the future money will be a decentralized crypto or an old fashioned fiat, I can't tell.
you're right, it is not essential it would be money in the future or not, certainly, at this time has become the currency bitcoin best available on the internet and it was more than enough. if many are aware of this, then surely peralahan bitcoin will be money in the real world, we just need to wait for it to happen
