about running a validator on testnet

[carameleon]

I read https://test.ton.org/ to run a validator on testnet.

client version :

At this moment I installed full node and it is running. And I was stuck at getting enough test tokens.

pow giver, large testgivers in here. It was empty.
e.g.,

The only way I've found is the Testgiver Ton bot. It provides me 5ton/hour. This is my wallet that I've tried to get small tokens from Testgiver Ton bot. But I believe it's not a way to have enough tokens to run a validator.

So, I'm looking for ways to get enough tokens to run a validator on testnet. But I have no idea which is the latest docs or approach. I would like to get 20000 test Grams to participate in the continuous validation process.

How can I have enough tokens for this purpose?
