If we get listed on another big exchange like BITTREX or UPBIT then we won't have to worry about exchanges ever.
No. SONM already listed on binance and it's the one of biggest exchange for now. Even though SONM listed on other exchange sites, i doubt the price will be affected/increased.
Yes Im agree with you another exchange will not affected the price much, I still have SONM some and not worry about my investment because I see the team still developing this project.
