yes definitely bitcoin stands for good only it was launched to make online transaction ease and barriers Less transaction and thus removing all old system from online transaction. and also it had benefited many user by allowing them to earn handsome amount monthly.
but on first place, it was used only by a criminals, that used it for bad activities like selling drugs, weapons etc.Now it has changed, we see many other activities that are legal and that make happen in the bitcoin world, we can invest, gamble , trade , buy , sell etc.
I'm not agree with that. On first time it was only used by miners and traders, mostly users that want to change the world, and want to bypass the banking system. Later some users used it for ilegal activities but this isn't a bitcoin problem, fiat system has the same problem you can't control what users are buying or selling.
Also gambling is ilegal on some countries.
