It seems Bitcoin Diamond has relation to Bitcoin because it share Bitcoin exact history up to block #495,866:
arent all fork like that ?
Sure, but it mean forks have relevance to Bitcoin. I sometimes read these forks just steal Bitcoin name, but with shared Bitcoin exact history, the name like Bitcoin Diamond is fair.
But at the end what matter is user support, so while Im very sceptical about Bitcoin Diamond, lets see what happens - privacy and fast transaction time might be usefull afterall.
yeah that all this fork about, but can forked coin replace the original coin ?
I dont think its about replacing Bitcoin, but about delivery something which Bitcoin cannot. For example I found Bitcoin usefull as speculative investment only and Bitcoin Cash for actual usage. Maybe this one can deliver privacy, so while Im very sceptical about Bitcoin Diamond now, Im open minded.
