Polkadot rolled out the last missing part of their Polkadot whitepaper and rolled out the parachain into testing and auditing. With this, polakdot supports a scalable multi-chain architecture. Once the change goes into production, the community will decide which features will be added in the future. This will make Polkadot flexible to market changes and gives it a huge benefit over other alt-coins. Polkadot is on my watch list since a while and I am happy that could invest now with the dip.
