Hi, i made the following transactions to my wallet:
4000, 5000, 5000, 12000, 1000
Im not in a hurry to stake, im long, but i want to understand if im doing something wrong, or its normal... 72 hours and nothing staked

As long as the wallet is unlocked you will begin stakingeventually. Sometimes i have also nothing for a day or 2 and then 10+ stakes on a day. Blocks will get split after time by itself so staking should happen more often
