While the value of what he sold, 5,050 Bitcoin, was $5 back then, you can imagine holding the same value of 5,050 BTC today.
In fact, I personally often read interesting stories about Martti Malmi in the course of the early development of Bitcoin, which is widely known in Bitcointalk circles as Sirius-m, he co-founded the revolutionary cryptocurrency as we know it today, it's no wonder that Sirius is considered a Bitcoin legend.
The moment of the first Bitcoin transaction that Martti carried out sold 5,050 BTC for $5 at that time and until now it has been immortalized and has become a very important thing in the history of Bitcoin throughout time.
Maybe yes, if it is in circulation as of October 2026, 5.050 BTC is worth $422.685.000 if multiplied by the price of Bitcoin at $83.700.
For me it is one thing to respect Martti until now, even though we all know he had sold most of his Bitcoin at that time, but it is an honor for Martti, he remains a loyal supporter of cryptocurrency/Bitcoin and one more thing Martti continues to contribute to the community, especially Bitcoin, this is an honor.
