Its not too late to hop on the train even with the market prices which are quite low at the moment.
OK and where may I exchange QCP. Where is good exchange. I dont no only china HUOBI and this is scam now. Thank you for ansver.

In addition to Huobi, the Quantston token is already traded on 4 exchanges, including the decentralized EtherDelta
https://coinmarketcap.com/currencies/quantstamp/#marketsI would highly recommend binance, the exchange is a very good competitor to Bittrex and offers something like 2 btc withdrawal without KYC- so you can keep some level of privacy... also QSP has very healthy volume on binance.
