Polkadot is one of the few projects that I'm very excited about for the development of the crypto currencies and their adoption, I think it will help a lot when it comes to decentralization and help protect the people from hyperinflations, 5 stars from me!

Bitcoin is the first ever cryptocurrency and it was created after the financial crisis in 2008, it's design is to protect people from hyperinflation that may occur during such crisis, and it gives people full control over their holdings without needing a bank or third parties to do it for them.
