If you hold your money long term in regular checking or even bank savings accounts you will become poorer, there is no doubt about that. Inflation will eat away at your purchasing power. You will struggle to find any product a regular bank can offer that will help you beat inflation. Poor people save, smart people invest. Put your money in crypto, stocks, real estate.
However, saving money could be a stepping stone so you can achieve your desired investment. You don’t invest immediately, you save money first, so you can invest for long term without pressuring yourself to take your profits after a short term investment period.
Inflation is inevitable, and it’s here to stay for good. So the best solution is, invest in bitcoin and eventually start to diversify once sufficient profits are achieved. But just a reminder, save some emergency funds as well. You don’t want to sell your bitcoin suddenly particularly when emergencies or financial crisis comes.
