Right know there are more than 50 000 unconfirmed transactions on Ethereum platform. There were many talks about sharding etc, but nothing appeared. While this issue remains every day centralized blockchains like Ripple and EOS are superseding Ethereum.
Most of those transactions have zero value and subsequently very low fees were paid for them. Those who can spare $0.09 for a transaction fee get their transactions confirmed within several minutes max.
Regarding the issuance of the BNDES token, I'm always a bit skeptical about those fiat-pegged cryptocurrencies, but, on the other hand, I'm glad overall that blockchain technologies are spreading around the world.
