No Krogmo Coins and Rank Points on Blast Network

So guys, I have encountered this when I was playing Blast Network. After a round, which I ended up last (again), I noticed a message about something that I don't have the battle spirit and it didn't give me Krogmo Coins or Rank points. I'm not sure about what triggered this, maybe cheating or playing really bad. I assume the former is the right one, but I only got out between two bombs by lag (or glitch), if that's what made the message appear. Anyone knows what's going on?

Well, thanks for the answer. I really wasn't playing really well that round, I managed to kill myself when I put a bomb and one of those rockets just hit me and I exploded, probably coincidence. Maybe I really need to get better at that..
as far as i remember, ther might be a minimum amount of bombs u have to drop. i dunno if they changed something or if i got it wrong, but last time i didnt get rewarded, i played pretty okay compared to the many not-so-high-skilled players back then, but i didnt use any bombs at all.
it really messed up bomberman imo
You get that message when you basically don't do enough in a match. It's to prevent n-afk lazers from playing and cheating coins/rank by just sitting in on every match and getting rewards for being there (since the game will kick you for being afk after a short period). If you want score, you have to really get in there and do a lot, make the most of the game. Being lazy has no rewards in this game.
