its depend on the SONM price right now. marketcap will increase if price go high. only milestones achivments can take the price up, i see no other reason for price pump.
4.6 million marketcap is too much low for a project like sonm its all time high marketcap is much more higher then current.
Anyone already knew if the token price is the one who determine how big their marketcap. It's simply price*total circulating supply, so if the token got pump, obviously their marketcap also going higher.
Why is it too low? Sonm always been like this for more than a year ago
At the moment this token is trading at the lowest price ever and volume is also not attractive maybe this is the big reason why price is going down and down there is limited liquidity available. This is active project they team is still working hopefully it could make comeback soon.
