What happened

Arweave (AR -2.64%) is a relatively small cryptocurrency but gaining in popularity, especially over the past week. It's up roughly 50% over the past seven days, according to data from CoinMarketCap.com. Seven percent of its gain has come over the past 24 hours, as of this writing. And this bump in price might have something to do with another cryptocurrency rising in popularity -- Solana (SOL -3.28%).

So what

Solana is down about 2% over the last 24 hours. But it's making headlines today because of a deal announced with FTX and Lightspeed Venture Partners. According to CoinDesk, the trio is investing $100 million in companies looking to build video games on the Solana blockchain.

Arweave differs from Solana. Its purpose is to provide data storage in a decentralized way. In December, Solana picked Arweave to manage its data needs. Therefore, as Solana's adoption increases, so too does the importance of Arweave's services. And with $100 million to spend, it seems more games will be built on Solana, creating a favorable-use case scenario for Arweave.

Now what

The cryptocurrency space is huge and full of dubious investment opportunities. It's hard to know what to listen to and what to tune out. However, one can be discerning by looking for cryptocurrencies that are actually getting used more and more.

In this light, it seems that both Arweave and Solana are being adopted, as crypto-gaming gains in popularity. There's more to consider when analyzing these opportunities, but for now, this is a good sign for these two cryptocurrencies.
