Again, adoption of blockchain technology isn's something positive to Bitcoin and crypto. These two terms are confused very often. Blockchain isn't same thing as crypto. Lot of big companies and banks are interested in blockchain technology, but it doesn't mean that they are positive about crypto.
This is especially true of banks and the public sector.They It is not so important cryptocurrency how important the technology of the blockchain.Blockchain is a cool technology that will be used in any activity in the near future.And apparently the Polish Bank will be one of the first who will begin to apply this technology in practice.
