Why not Bitcoin?
While BTC could be good enough as currency on the island, it’s more because by having your own token, you get to set the rules of the economy around that token. e.g. stake to earn, stake to stay, set in a smart contract to award discounts, perks and benefits IRL or in the metaverse, transact off-chain with zero transfer fee within your own closed network, set in smart contract to work dynamically with the NFT collection of the project or for community funds collection, apply algorithmic stablecoin, apply governance feature to the token etc. With BTC, this would be difficult or impossible to cater for. Many Web3/NFT projects have their own “in-game” tokens for these reasons.
*examples above are not specifically for STC but what is also done with Web3/NFT projects elsewhere.
Some people might think STC is too volatile for real use. Actually, a token like STC might not eventually be as volatile as you think, because unlike BTC (or ETH), our island token is:
(1) not traded on every international exchange in the world, and hence
(2) not subjected to wide speculation e.g. leveraged futures trade
(3) not subjected to market manipulation and spoofing (e.g. future and spot ETFs)
(4) not as subjected to sentiments/FUD e.g. due to dXY, FOMC meetings etc
(5) not as subjected to hype e.g. sudden adoption by institutions like the Big 4, Amazon etc
(6) not used as reserve liquidity by unscrupulous exchange which they then sell off to save their venture (e.g. FTX/SBF, LUNA/Do Kwon, Celsius/Mashinsky et al)
(7) not confiscated by governments from illicit trade and dumped on the market (e.g. Silk Road, Mt Gox)
(8) not subjected to halvings, hashrate fluctuations, difficulty adjustments, or open BIPs/EIPs
(9) limited in usage strictly defined and confined within the boundaries of the island and its own economy, marketplace and ecosystem.
…and so eventually, once in its proper use, once we move from sentiments to fundamentals, it’s possible STC could even be more stable than BTC (or ETH), short term or long term. At least, that’s how I see it unfolding based on the merits above, as much of a fortune teller I am also NOT…
And as much as Satoshi Island is a real estate project, it is still a Web3/blockchain/crypto project at heart. There is a lot of smart contracts at play that having our own token presents greater functionality and advantages. It has a metaverse that runs parallel to it, and as independent as that metaverse may be, it is more feasible and practical to have a token that ties the use case/usage in both metaverse and IRL environments.
Just my 2 STC.
