I have 500 billion, you know.
About
Back when the term "cryptocurrency" hadn't even reached the public consciousness, Guest, a visionary student, spent 10,000 yen of their allowance to buy a cryptocurrency called "GoodCoin." 15 years later, its value has skyrocketed 2.5 million times, resulting in assets worth 25 billion yen. Since then, Guest has reinvested those funds into various other cryptocurrencies, real estate, and stocks.
Currently, Guest holds approximately 50 billion yen in deposits and cash. Including gold and real estate, their total net worth has reached a staggering 500 billion yen.
Leverage this abundant capital to expand businesses, increase investments, and seize all the wealth and fame you desire.
...Oh? It seems there's a reunion of former classmates coming up in your hometown. I wonder how those guys who used to look down on and mock Guest are doing? ^^
