I think people in rural area needs to be financially stable first before knowing bitcoin.
Do you mean Before Knowing Bitcoin?, or investing in Bitcoin?. If so then your are wrong, getting to know or the knowledge about Bitcoin does not have anything to do with poverty. Too it's wise to get to know of Bitcoin to actually start any investment into Bitcoin.
Therefore, to know Bitcoin is a different thing while if you talk about being financially stable before investing in BTC then I agree with you.
