You said you did not  buy the coin again as he asked you so, why the skeptic if you were going to be scammed?
However, you are safe as long tou did not follow his instructions so there is nothing fearful to loose but truth be told, all that statement of the anonymous is phishing and you too would had questioned him about how he got your contact because I see he is defected not in your contact file and in this crypto space, we are ought to be very careful when with the unfamiliars.
I will also sanction you for giving him such an attention all those while because while you think you are making fond of a scammer on that form, don't doubt that you may out of your selfcontrol fall on his trap because you will be tempted with the sugarcoated words of quick and massive profit.
