Hello there @hash-tag,
This is indeed a very famous quote and it can be applied in the current situation I think; especially relating to DeFi which I stay away as it seems too "easy money" and we also have another expression in Finance:
"There is no free lunch!"
Cheers, and beware :D
True that, mate. No free lunch. I think I have learned my lessons in crypto. Now, I remain extra cautious. Thanks :-D
