The best place to buy cryptocurrency is on decentralized exchanges like 1inch or Paraswap. These allow you to buy crypto directly on the blockchain, without needing to trust a centralized exchange. This makes it a more secure and private way to buy crypto. If you prefer to use a centralized exchange, then Binance or Crypto.com are two of the most popular and trusted exchanges. They both offer a wide range of coins and tokens and are relatively easy to use.
