The main reason why BOOM is not going up is because investors are investing in coins that are launched 3 to 4 years back and are mature now. BOOM being new in the market is facing pressure but surely will overcome this pressure.
Every coin has its day. If BOOM is not going up right now this does not means that it wont up in future too. Just buy this and HODL, BOOM is yet to take its first massive jump, buy it before it takes that.
