Re: [ANN][SEM] Semux - Official Thread - 🚀 BTC Airdrop Now 🚀
since my btt rank upgrade,do i need to upgrade my signature or not 
NO NEED. It's automaticly updated.
What other way is there to earn SEM?
You can buy from otc thread, you can get from the signature or you can get from btc airdrop. Currently, there is not a way to obtain it.
Although i saw a semux faucet which is giving 0.3 semux for 12 hours but i'm not sure it is legit.
