Hello
Thanks for the ann thread! I wann know guys what is the minimum amount needed to invest in order to join the sale? Thanks in advance for your answer! )
Welcome! There is a relatively low minimum. Coinexchange is where Safe Trade Coin - XSTC is being traded.
Currently the only trading pair is BTC, but that will obviously change in the future.
