Is Bitcoin Mining Still Worth It

[ScrumbleGames]

Is an Antminer s9 still profitable, how much does or could it make in a day? Would you reccomend buying more than one to start out with? Also to add on is an Antminer s3+ a good choice or is that out of date. What's the minimum mining speed I need to see any good results, sorry for all these questions but it's good to know before I spend a bunch to mine.
