I received a email from blockchain wallet last year stating I received 100 STX tokens which were non-transferable that time. It stated in faq , the received STX tokens in blockchain wallet will be freezed for a year and then can be transferred. As you guys knows , now 100 STX is worth $50 , it was just $10 a year before though. I think the tokens will be transferable from January 21 , 2020 , exactly a year after the distribution of tokens. So I wanted to ask if you guys know any exchanger site where you can directly exchange STX tokens to altcoins or BTC. Let me know your opinions guys.
