I want to say, DOT is not a stablecoin. Although the price is quite stable, DOT or Polkadot cannot be categorized as stablecoins. dot is a utility coin and the price will change from time to time with market developments, so it will not be very stable. but regardless, DOT is still worth investing in. The Polkadot network is still growing and the potential of this project is huge. I've been following this project for quite some time, even since the price was under 5$. I have been observing this project, and my conclusion is that polkadot is one of the Dapps network that is good enough to compete with ethereum.
