5 seater 25-50p NL. Nasty..or great flop ?

[concussed]

I have in BB. 4 players in a slightly raised pot.

Flop comes !

SB checks, i bet Quarter pot, followed by a Re-raise (from quite a tight player), a Re-Raise, and an ALL IN from the original checker making the pot £30.
I fold , the other 2 go all in. (we were fairly well matched in cash btw)

The player who checked after the Flop won with .
The other player had , and the other player mucked.

Any thoughts... I know i'd have lost, but did I do the wrong thing by folding

[Triple B]

Its a tad hard to follow since we don't know the size of all the raises or the stack sizes, but these seems a standard fold. You are usually crushed here and your boat outs are not always good.

Also...never bet 1/4 pot pls.
