Can developers explain why the quantity of available tokens is so unstable?
I have monitored how many tokens are available during 2 last days and I found that it is changes so strange. first it was something about 9k, then the quantity decreased during few hours, but a little bit later it was -10 (minus 10) about 30 miutes. Later it come back to 8k, then decreased gradually to 4k+. After, few times I found that the quantity is 0.
But today it is again more then 7k.
What is it? It look very strange for me. Project is really very interesting but I'm afraid that it can be scam.

Please advise.
