this is right time to buy semux because btc crashed ,but semux dropped a little ,i think if hit exchange ,there will no more cheap coins.
Semux was given out as an airdrop. Typically, those coins dump heavily first on getting listed on an exchange, and recover later.
There are many potential coin so why Semux? People are probably waiting for it to be listed on the major exchange but that is not easy, almost small exchanges will make the coin more disastrous.
