Without any evidence being posted here I guess you mean a non-existent/faked name/account on Instagram or other social media's, right?
Any real trader or investor already knows that these are fake accounts begging for your money/bitcoins.
I tested one of those Instagram accounts once upon a time and just for fun; started with 50€, got 100€ back, tried with another 50€, never got it back, IG account was closed. lol
Today I am always reporting such "Binary Options, Forex Trader, Bitcoin trader, account manager" whatever scams on Instagram. Just use the "spam report" button when visiting such fake profiles. Instagram will delete them asap.
