After they installed in groups the wallet, quick setup CPU-miners and were all looking happy and fascinated on their screens... 5min - 10min, but nothing happened at no computer. Nobody mined a block - after 10min I was looking in detail & saw that someone placed 800MH on our "teaching-coin"
So we have no for sending now, haha.
Really funny and obvious situation, maybe you would have made a course about how it is useless to send too much hash power into a new coin, as the only effect is difficulty skyrocketing. A blockchain always tries to release blocks at a stable rate.
