Here's my approach. I sort the tags by payout. Then I go down the list starting from highest payout and I start picking appropriate tags. Avoid irrelevant tags so you don't get flagged. This approach will increase your exposure. "millions" and "litecoin" aren't even in the main list. Using my approach one result would be: bitcoin; money; funny; crypto-news; crypto. You could be more aggressive than that but your exposure would be much bigger than your original tags for sure.
