Where to buy Polkadot
Interest from investors has resulted in Polkadot (DOT) being made available on a range of cryptocurrency exchanges and trading platforms. The former focus entirely on the crypto sector, while trading platforms such as eToro offer a range of markets including stocks, forex and commodities, as well as cryptoassets.
Cryptocurrency exchanges are categorised as being either centralised or decentralised.
- Decentralised exchange (DEX) — a person-to-person marketplace used for buying and selling DOT and other cryptocurrencies. Trades are carried out directly with another investor, and buying DOT on a DEX can usually only be done using another cryptocurrency.
- Centralised exchange (CEX) — a marketplace for buying and selling DOT on the exchange itself. The exchange acts as a broker of Polkadot tokens, and they may hold positions in DOT to sell to willing buyers.
Tip: Trading platforms are typically more beginner-friendly than centralised exchanges, which tend to be more beginner-friendly than decentralised exchanges.
How to keep and store Polkadot
As with any asset, ensuring Polkadot is stored safely is of paramount importance. This is particularly important in the cryptocurrency sector. There are a range of established methods for storing Polkadot (DOT) tokens:
- Cold wallets — more akin to an external hard drive, DOT is stored offline, making it safe from malicious entities.
- Hot wallets — used to store DOT online, hot wallets (such as Exodus and Atomic) are specialised cryptocurrency wallets that can hold a range of cryptoassets.
- Broker platforms
If you buy Polkadot using a broker platform such as eToro, your tokens will be held securely in your account on that platform.
Learn more about Polkadot
Polkadot has innovative features that allow it to build on the success of the Ethereum blockchain. It was created by Ethereum co-founder Gavin Wood in 2016, with the intention of improving the functionality and interoperability of blockchain technology.
The core Polkadot blockchain is supplemented by parachains — separate blockchains that run and process transactions parallel to the main chain — which can be developed for a number of use cases.
These parachains can be used to develop services and decentralised applications (dApps) with inherent value. They also benefit from having the same levels of security as the main Polkadot blockchain, making them a relatively safe way of exploring the full potential of blockchain technology.

FAQ
- How many Polkadot (DOT) tokens are there?
-
DOT is inflationary in nature, and so the cryptocurrency’s total supply varies. At the time of writing, DOT has an annual inflation rate of 10%, with no maximum supply. As new DOT tokens are created, some are used to reward validators and nominators for helping to keep the Polkadot network secure. The remainder is sent to the Polkadot Treasury.
- What is Proof of Stake?
-
Proof of Stake (PoS) is a protocol used to ensure that transactions on a blockchain are recorded accurately. Polkadot uses the PoS approach which is more energy efficient and faster than the Proof of Work (PoW) protocol used by other cryptocurrencies, such as Bitcoin.
- Is buying Polkadot (DOT) safe?
-
Regardless of the asset you are buying, it is important to acknowledge market risk — the unavoidable risk that the price of an asset you hold could fall in value. Equally, operational risk, the risk that your assets can be lost or stolen, also needs to be factored in.
Continuous security upgrades by service providers in the crypto sector have gone a long way towards ensuring that Polkadot is as safe to buy as other assets, such as stocks, bonds or forex.
