The L7 a/k/a L7 DEX scheme describes itself as a decentralized asset management protocol based on Web3. The website is very secretive and doesn't reveal much more, which is not good for a financial scheme, to say the least. This scheme also operates its own crypto token, L7 (symbol: LSD), which currently has a market capitalization of around $5 million. L7 is a multi-level marketing (MLM) scheme and recently launched its own L7 crypto debit card.
