Deflationary tokens are good but you need to be careful while playing with them. BOOM has gone up by 400% in one day and it might remain bearish for many days to come. You need to be wise in order to carefully chose the time for investment.
But this is clear indication of the fact that its not a shit coin rather a sleeping coin. When it woke, it roar hard. Wait for BOOM to come to its previous price and buy for long term HODL.
