Polkadot is a great Defi project in my opinion, and one that has the potential to replicate in the Defi space the same type of influence that ethereum has in the smart contracts space.
Thr Polkadot blockchain is like a robust network that allows the integration and combination of different Defi platforms such that real life-like financial services can be gotten through the blockchain.
This makes it very valuable in my opinion and its tokens price relatively very much undervalued
As far as the products or services available at polka dot we have to wait and see how will they make a difference and what new and better things they are offering till then it is just kind of speculation but as the confidence is high the price of their coin is growing and with this momentum i do not think that 100 bucks will be difficult to achieve for dot.
