Ledgerium Airdrop
Ledgerium is a company that brings Blockchain to the accounting and audit industry. The whitepaper is well structured but the team has no linkedIn links.
The amount of 5 LGUM you receive is ridiculous low because 1 ETH = 120,000 LGUM. Therefore the 5 tokens are worth less then $0.03. That's a huge downside.
Airdrop finished
Estimated Value : $1.5
