Hi guys, this morning I’ve seen 500 + difficulty in the testnet, it means jaws are between us?

Yesterday it was around 50 - 80 +, now it is ten times more.

I’ve seen, this morning, the solution of 10 blocks in less than 10 minutes, in this way the supposed slow mining will be a dream, is it correct?

Can anyone help me in understanding the situation, thanks.

Ps. with 80+ I was able to find (with CPU) a block every 4-5 hours, now nothing to do, I’m out.

Thanks in advance for any answer.
