I have a question, what is better? ... only one block of 50,000 ZEIT or several blocks with different amounts. I just bought ZEIT and once blockchain finished the upgrade. I would like to know your recommendation.
Depends on your goals,
If your only goal is earning zeit interest:
Then as few blocks as you want, and only open it every 25 days or so.
If your goal is also to help secure the Zeit Network :
Leave your Zeit Wallet online as much as possible,
Keep no less than 5000 zeit per block and a max of 1 million zeit per block.
Keeping ~1000 or 2000 blocks total in the wallet.
FYI:
You can just initially put it in a few blocks , and it will automatically split in half if it stakes in less than 30 days, and will not split if it takes over 30 days to stake. So after a few months , it will be tuned to help secure the network even if you don't worry about it at the present time.
