The DOT coin met the last bull cycle on a wave of success. In November 2021, its price was almost $ 55 per coin. This, unfortunately, was its record.
All the following time, Polkadot only got cheaper. Throughout 2022 and 2023, it was in the range of 4 to 5 dollars.
And only the subsequent bullish year of 2024 allowed it to rise in price to 10 dollars for some time and later fall back to 4. The prospects for this coin are the most vague.
Polkadot can grow to 20 dollars only if Bitcoin rises in price to 100 thousand.
I recommend buying it and storing it. After all, if Bitcoin rises in price from 60 thousand to 100 thousand by 40%, then the Polkadot coin, at the same time, should rise in price by at least 5 times. This is a good investment. But your crypto portfolio should never contain just one coin. Always mix it up with different coins.
