Betting on this flop is retarded 7 handed. For 50c you may well fold out a lot of weak lows and flushes as well chances to catch straights, sets, boats, two pair, etc. This is a check/call flop, or check raise if it's a loose table and someone soon after you bets and gets heaps of callers. Get a nice big pot going so you can hammer the later streets and keep as many people as possible in the hand.
