This is just my personal feeling, groundless. If my idea is wrong, please correct it.
I learned about cryptocurrency only last year. I was lucky to know several senior players. I found a preference among my friends. Friends who support bitcoin will despise other coins, and he will scoff at new play items in the market. Friends who support Ethereum are very interested in new projects and will understand or participate in them. Over time, I feel that the friends who support bitcoin are conservatives. He only agrees with bitcoin; The friends who support Ethereum are energetic. I'm just a feeling of myself. I don't mean to offend anyone.
