nemanjatrifunovic.substack.com is a Substack publication run by Nemanja Trifunovic, focusing on programming history and retro computing. For a personal blog, it checks the right boxes: a valid SSL certificate, enforced HTTPS, and a clear About page with contact info. The site also has privacy and terms pages, which is more than most hobby blogs bother with.
What should give you pause? The site is very new — no web archive history — and it loads 148 external scripts. That script count is typical for Substack's built-in features, but it's worth noting if you're privacy-conscious. There's also a mention of bitcoin as a payment method. That could be a donation link, but it's unusual for a blog that otherwise uses standard subscription payments. If you're just reading free posts, there's no risk. If you're asked to send bitcoin directly, treat that with caution.
Overall, nemanjatrifunovic.substack.com looks like a genuine tech blog. The absence of a long track record and the bitcoin flag are the only reasons to hesitate, not to avoid it outright.
