Is Bitcoin mining pools safe to invest with? I happened to follow a few Bitcoin related profiles on Instagram today and within a few hours received about a dozen  messages from ppl asking if i wanted s fast secure return up to 5x my investment.  Of course i immediately assumed it was a scam then I did a Google search on.mining pools.  I haven't read where it's a scam or even a high risk move?  

Can anyone give me advice on if I should even entertain the idea.  Or is it something that is just too good to be true.
In general, get rich quick schemes are a scam.

Mining pools themselves are safe to mine with, but I do not know of any official investment schemes. Do not send your money.
