Everyone starts somewhere. The person with $100,000 invested today once had their first $100. The difference? They started. Your turn. Let Mamo grow your @USDC, always earning the best rate and auto-compounding returns without needing to lift a finger.

Last week Finnair grounded multiple A321 planes because they washed seat covers WITH WATER and they had to replace them ( https://t.co/KZqBC2ojMF). Today I flew on Iberia A321 with somewhat exiting emergency exit door 🤷‍♂️
