It just depends or the individual whether they're only big on Bitcoin, big on both altcoins and bitcoin (with Bitcoin being the primary asset choice) or they might have same level of interest across all crypto projects. For instance, I'm big on bitcoin and a few high cap altcoins (won't mention name) and you're on mostly bitcoin with some interest in other projects. Another person might just don't like bitcoin but is totally in on altcoin projects.
This is because as humans, we're all different and there's enough more categories than OP or other community members have commented about.
