I deposited about 100 million yen into Backpack, and used half of it, 50 million yen, for DeFi investment. The interesting part is that lending automatically starts just by depositing. It's a system where points accumulate based on the volume of lending transactions, but since users in Japan can't use the trading feature, it seems they get a pretty substantial boost in points for lending. In other words, the restriction on trading is compensated by earning returns through the operation.
