“Unfavorable prices” at the CCEDK exchange? That exchange doesn’t suffer from low liquidity, it suffers from no liquidity. It’s impossible to convert $5000 of BTC into USD on that exchange, because there are currently zero buy offers on the BTC/USD order book. See https://www.ccedk.com/btc-usd
What is the best way to get USD onto that exchange for buy support, other than the direct the sale of NBT, which KTm already has covered?
