I can't speak for exact time frames, but I have about 40,000BLK and my coins just "matured," and it says it will mine in 6 hours.
Depending on the network weight, coin age and the total amount of coins in a wallet can speed up proof stake mining process. Normal staking period takes about less than 500 blocks or 8 hours to mature.
Thanks for the info. I'm fairly ignorant. Some might say "shouldn't you know all about something you invested $10,000 in?" Yes, I should. But I don't!

I just saw they were fairly low, and thought now might be a good time to snatch some non-ICO coins at 19 cents. I'm sure I've doomed Blackcoin now, if my previous history is any indicator. Now that I bought in, I fully expect 1 cent BLK
