Bitcoin is sure not gambling , We know how to get it and invest through it, and it can act as an intermediary.
Bitcoin is purely a digital currency and there are a lot of sources to earn from bitcoin I know a lot of people who are doing gambling here and they think its one of the fast way to earn but I think they are wrong because in gambling you can lose and if you want to earn on daily base with fast way so you can join on line trade because Im also earning from on line trade and its very useful for me and I dont need any gambling to earn.
