Coinbase · 
Coinbase is a secure online platform for buying, selling, transferring, and storing cryptocurrency. In April 2021, it was listed on the Nasdaq exchange and became the first major cryptocurrency company to go public. Many mark this event as a significant milestone in improving the image of blockchain as a legitimate industry. The exchange's popularity also led to a popular phenomenon known as the "Coinbase effect", where cryptocurrencies saw a huge surge in price following their listing on the exchange.
