The way BOOM was going it was very much expected that it will stall at some point and this is the point now. Now those who have invested in BOOM need not to panic rather just show some patient. There is notthing to worry if you have bought this coin in recent one month or two. Market is bearish and so are alts.
If those who have bought in the last month or two and now have profited with BOOM, then it is better to sell now because take profit from the start is always better than having to wait long for higher profits because it is still not sure to come on BOOM.
