The dot coin is a coin of the Polkadot ecosystem and we all know what hype it has created in the market in recent times. It is currently priced at around $21 which is 60% below the ATH price. At present, its price is very low but many people call it Ether killer for some special benefits. As it is more versatile than the Ether network, it gives developers more than one platform, they can also work on new crypto on the same platform. Basically, developers find it more convenient and comfortable to work on Polkadot. This is why Polkadot is currently more popular among developers and its investors are basically developers.
Dot is much newer than Bitcoin and Ethereum so I think it will take some time for more investment to come. However, since it has taken a strong position in the market, I am bullish about it in the long run. I think the price of the dot can easily cross $100.
Anything below $100 would be considered a bargain. Polkadot is one of the few projects which deliver concrete results to the mainstream world instead of being hyped up by its supporters (like it's the case with Solana and "meme" coins like Dogecoin and Shiba Inu). It's a smart contract platform with an emphasis on scalability, using Ethereum's tried-and-tested EVM for the deployment and execution of decentralized applications. I'm pretty sure mainstream developers will choose DOT for the launch of new and exciting dApps in the crypto/Blockchain space. It's as good as Polygon (MATIC) and Avalanche (AVAX).
I believe DOT's price is declining because of the bear market. This might be a great opportunity to grab some cheap coins before everything goes back up again. If it gains traction, then it could easily reach well above $100 per coin. Ultimately, it's all about the usefulness of a coin (not the price). As long as Polkadot is useful, it'll last a lifetime. Just my thoughts
