Lets put the lack of exchanges concept in perspective. Perhaps you want to buy a new car. You have plenty of Ford, Chevrolet, Toyota, Dodge, Mazda, Volkswagen, Subaru, and Honda dealerships where you live. They speak the same language that you use. However in order to buy a Hyundai, you have to go to another country to buy it and they don't speak your language. There is a high probability that you would not buy a Hyundai.
This is the dilemma with STEEM and SBD. As a currency, if it is not made available everywhere, then people would likely use something else. In comparison to other currencies ranked in the top 50, STEEM and SBD are severely lacking access. When people don't buy it or use it, the currency has little value and thus the price will remain low.
Other currencies have dedicated teams aggressively convincing exchanges to list their coin. STEEM seems to leave that task up to US.
We need to let HitBTC know that there are many people that want STEEM and SBD wallets fixed on their exchange.
