Well to be honest dude, there are some altcoins that are much more good and better than Bitcoin just like Ethereum.
But since Bitcoin was established the big community in the entire world, now wonder why lot of investors embraced it maybe
because of its unique features it has that's all what I had noticed.
Please define 'good' for us.
If I was looking to put money into an entirely digital asset with zero value beyond the belief users have in its value and utility I will be looking for network effect, security, attack resistance, decentralisation, competence and the spread and depth of development.
If something has none of that but 60 second confirmations on its one data centre chain plus a 'partnership' that consists of a canned fob off from whatever company they're lying about that's not going to sway me.
