The fact that even at £100,000 you would only earn £20 interest is actually rediculous. Meanwhile the bank is taking your money and lending it out to over people for anywhere between 3-20% APR, especially for the unfortunate people who are in overdrafts getting charged an extortionate 20% interest.
Why keep your money in a bank and earn a tiny 0.02% interest when you can earn 6% interest on stable coins using crypto instead. Let alone if you stake crypto itself you can get much higher APR if you want to take on more risk.
Take your money out of the bank and pay yourself some interest
