But for rains, is it random or are there requirements that must be met?
https://help.stake.com/en/articles/4942138-stake-promotions-and-bonusesYou can check above link to know the requirements to be eligible for any bonus including rain in stake. In short, yes there are 2 requirements to be eligible for the rains. First is to wager 4k during the last 7 days and second requirement is verification level 2. Coming up to bonus drops in telegram, the requirements are always being informed along with the bonus drops.
Yes this requirement was updated this year to reduce spam activity in chat rooms the most effective is KYC because not everyone wants to do it
I've been inactive in the chat room and haven't received rains since 2021 and the last time I sent rains was about 2 months ago
last week my friend sent a screenshot that one of his friends got $1000 from rains at that time whale sent $5k for 5 users.
