I heard about Burency (exchange and blockchain development platform based on middle east) a lot through telegram. They have over 100k members in telegram group. They've recently partnered with huobi. They also featured in a lot of news coverage.
Their native erc20 token BUY are on ICO. Almost 47% are sold. My question is should I invest in buy token

Will it be a good choice

Or any exchange token suggestions other than BNB and HT.
It looks like if that was another fake claim by burency. Huobi has no announcement to create a partnership with burency. The credibility of this project must be talked as the big exchange site will always announce the partnership.
It will not be a good choice and never. It's better to stick into the upcoming exchange token from bittrex, bithumb, or invest in the existing coin like OKB.
