Likewise, while cryptocurrencies offer the promise of revolutionizing traditional financial systems, their current level of adoption for practical use remains a matter of contention.

Striking a balance between speculation and utility will be key to determining whether cryptocurrencies can truly achieve their intended transformative potential or remain a speculative phenomenon in the financial world.
Take note that it is not all cryptocurrencies that are decentralized p2p money that is different from the current financial system, this very use case is for BTC and not crypto which includes altcoins and tokens. Cryptocurrencies that have utility are being adopted for all the use cases they offer, while there are some coins which are only useful for speculation.
The difference between speculation and utility is clear, a coin like BTC has its utilities, and speculation is one of them, because you can buy it and expect to sell it for a higher price later, but that's not its only utility, it is also decentralized money. But there are certain coins that are only useful for speculation, and because they lack any real utility, they don't get any adoption and they become useless after sometime.
