5. Coin burn
Yes, the mystery is finally solved.
5. Coin fork
5. Coin term
5. Coin chart
That's all i can think as of now.
It was "
coin burn". And besides, "
coin chart" has one character too many, so it wouldn't fit this time around. Also, you can only make one guess per term. So if you are submitting a guess for word #5, you can't submit multiple ones.
One more round coming up in the next couple of days and then it's time to end this challenge.
