Following NFT hype and growing demand in the DeFi community, the price of cryptocurrency Solana or SOL more than tripled during the summer of 2021. This had all but evaporated by the end of 2022, as a price of 151 U.S. dollars for SOL on Jun 30, 2025, was similar to the price of Solana in early 2021. The collapse of crypto trader FTX in 2022 especially impacted the cryptocurrency, as FTX and its sister firm Alameda Research sold a large amount of the coin to avoid bankruptcy. The Solana protocol is similar to Ethereum in that it can allow for nun-fungible tokens to be created ('minted') or traded. Solana, however, uses a technology called 'PoH' or Proof of History, which allows it to reach high transaction speeds. The Solana Foundation - the creators of the protocol, based in Switzerland - claims they could reach up to 65,000 transactions per second compared to 16 for Ethereum. Additionally, Solano had no transaction fees or 'gas', unlike Ethereum, which had growing transaction costs. These two reasons combined - Solana being deemed cheaper and faster than Ethereum - turned this relatively young protocol into a breeding ground for NFT projects in August 2021.

The price of the native coin from BNB Chain (formerly BSC) grew by 50 percent in late 2021 but was much lower in 2022. On June 30, 2025, for example, a single BNB coin was worth more than 654.92 U.S. dollars - a value that is very different from the all-time high of 600 U.S. dollars in November 2021. Regardless, Binance Coin ranked in the top 10 most expensive cryptocurrencies in 2022. Noticeable is that the price increase of BNB in November 2021 coincides with a similar price change for Ethereum (ETH) - a cryptocurrency where BNB initially originated in 2017 before coming to its own years later. BNB’s history: From reward token in 2017 to an ecosystem after 2019 As the name suggests, Binance Coin or BNB originally started as an extension of the Binance.com trading platform - the most used cryptocurrency exchange in the world. It initially functioned on the Ethereum blockchain network as an ERC-20 token, offering incentives to owners like reduced trading fees, affiliate rewards, or a lottery ticket system (“Launchpad”) that let users invest in new, Binance-selected crypto projects. In 2019, however, BNB moved away from the Ethereum network and migrated to Binance’s self-developed blockchain: Binance Smart Chain or BSC (called BNB Chain since February 2022). Here, BNB started to support a chain that initially did not focus on hosting decentralized apps but focused on high transaction speed and being able to handle large amounts of traffic. DeFi and GameFi: the main segments for BNB BSC, however, made significant strides in 2021 partly due to traffic overload and high gas prices on Ethereum as well as the growing interest in both Decentralized Finance (DeFI) and NFTs. Much like Cardano, Solana, and Terra, Binance Smart Chain consequently became a valid alternative to Ethereum: The total value locked (TVL) of BNBs blockchain within DeFi, for example, ranked only behind that of Terra and Ethereum in early 2022. Another area where Binance’s blockchain and token play a significant role is that of GameFi - or “play-to-earn” blockchain games that are powered by cryptocurrencies. Some of the more well-known and most popular NFT games like Alien Worlds and Axie Infinity run on the blockchain behind BNB.
