Alas, there's really not much technology to discuss

For things like BTC and ETH, which have financial and political significance, we need to look at economic trends

For most coins, we need to see what the whales think; if there are more long positions, they'll dump, if there are more short positions, they'll pump. All your positions are transparent, it's not much different from offline gambling

Especially for coins promoted by BN, 90% of the chips are in their hands, focusing on ratio contracts. 😋
