Hold on, you probably thought Bitcoin was a crypto? Crypto has morphed into an industry where centralised projects run by a team are marketing themselves as crypto when they are just ponzis at worst or MLMs pyramid schemes at best. A pyramid project is one that aims to get as many people as possible to buy into the project early and sell at the top to the later entrants, enriching the owners of the project and early backers. This is the status quo of over 90% of all crypto projects, pure affinity scams claiming to be the next best thing after Bitcoin. They have overshadowed the crypto industry leaving just a few utility projects like Stablecoins and others. Bitcoin has distinguished itself from the majority of crypto projects because it is truly and fully decentralised, it has a fixed limited supply making it deflationary. Saving in Bitcoin is long-term wealth building while most of Crypto is get-rich quick schemes or gambling in a virtual casino which are just not sustainable.
Stablecoins are in a category of their own, they are not speculative and are pegged to the value of the Dollar (eg, $100 can buy $100 of a US pegged stablecoin like USDT or USDC). However stablecoins are centralised and transactions can be frozen or seized at any time by Government request. Stablecoins are suitable for cross-border transactions and sending value since they are pegged to fiat currencies, hence the name stablecoins.
