With current computational power, the last BTC will be mined in 2140. With 17 million already mined I don't think there is much benefit in mining BTC.
No, I am not that fortune to have One BTC in my wallet. Just few ethereum though
The hash rate is at or near all time highs which tells us there's a ton of benefit in mining BTC otherwise they wouldn't be bothering. They certainly are not doing it for fun. I'll bet most miners do not care in the slightest about what they're mining as long as the dollars keep rolling in.
