Marketing. You could have made an official ANN post and offer a bounty program so you can get the word out. You would have had people making translations (reach more investors). Could have set up a discord and a telegram,fb and twitter. Another reason maybe be US based exchanges are a bit scary at least me to. Uncle Sam will shut that down if it's not done right. But I think its all marketing.
Totally agree, you need a good marketing team, without good marketing you are going to be crowded out, second reason is that since the beginning of February, the alts have been down in price, which wil naturally reduce demand for everyone. Not to worry this will all reverse, but get yourself clued up with some marketing techniques. Traditional & or crypto marketing is needed.
