I think that Bitcoin is pretty safe to use but there are always scammers active so look out for those people.
If you are just doing your own thing and not pay other people attention you should be alright.
Yes you just have to watch out for scammers indeed they are the biggest thread cause they are basicly everywhere.
Alot of gambling sites, investments etc are scamming and running away with the money cause it's anonymous anyways so always be careful
