I dont believe you were honest about listing HEAT on Bittrex.
Your beliefs are yours and as often is, they're no match to knowledge from source that's closest to the truth. Maybe I myself know best what I talked with Bittrex. I asked about co-operation for escrow + listing a new, major ICO. HEAT name wasn't being referred to, as it was still secret. So of course they hadn't heard about HEAT.
See how easy it's to make faulty conclusions about the "dishonesty" of someone based on your own, limited beliefs?
Because you stated this..... "Prior to HEAT ICO I've talked to Bittrex personally about listing HEAT". Now you are saying HEAT was not mentioned. Without explanation for this glaring inconsistency, you shouldn't be surprised that people would conclude something dishonest/disingenuous went down here.
