I would suggest
https://t.me/asianwhales this free channel. They have their VIP channel with 1-time fee 1.5 ETH which is expensive for me at the moment, but it seems that they know what they do there
Seems to be 2.5ETH now.
wow, really? way to expensive, but on the other hand most of groups have pay per month/week palns, so all in all Asian whales might be cheaper
