Hello,

I have been researching about blockchains and stuff and it all seems like a big scam. It’s not sustainable and can be replaced by a simple database.

is there any legitimate use cases of blockchains or it is all just a big scam?

    Using it as a currency which requires no third party for transactions is a legitimate use case. See current payment processors vs Steam conflict for why it may be a good idea. There are a lot of times when it’s not a good idea either.

    However the price must be reasonably stable and transaction cost low. Don’t think any of the major CCs qualify.

      Swift exists though? There is really no need for Credit cards or other payment processors.
