I forgot to come in here and report that my 50 million block staked the other day. It took 26 days to stake, at the time it was showing 82% chance of staking so I got lucky however most times I have seen my coins stake when its over 80% within 24 hours. This time instead of selling 30% of my stake I only sold 10% as now the diff is getting higher I thought now is the time to also build on my stack to try and stake quicker next time. That 10% went into buying more 421 coins.
It's day 12 now for my 119 million stash (altogether in one block), and 28% chance to mint in 24 hours. Difficulty has gone up from 26000 when my 91 million coins staked to around 30,000 today
