Why are so many people here prone to this kind of dumb hyperbole? Yes, Chris could probably get some more money out of his "fans" if he was clever and savvy. Could he ever be "incredibly wealthy" because of Sonichu? I strongly doubt it.
His peak on Patreon was $950, which wasn't sustained for more than a few weeks. But let's be extremely charitable and assume that with smart self-promotion and management and routine delivery of pledge rewards he could DOUBLE that and keep it going. You're looking at about $23k/year. That could absolutely make a huge difference in his life and help move him away from the brink of financial oblivion, but it's hardly a "goldmine" and it completely hinges on the assumption that there are enough people out there interested in Sonichu who would gladly contribute to his Patreon if only he offered more frequent updates, which is not what I'd consider a safe bet.
Be realistic. Sonichu has a limited audience. Normal people do not care about this shit. Chris might be able to make a living off of his weird e-fame for the time being, but he'll never be "rich" by any reasonable first-world standard.
