better to invest in bitcoin, gold maybe more secure, but bitcoin has more potential to grow
saving money in the bank, will only mean losing them in the long-term with the current high inflation
I believe to this that Bitcoin has more potential to grow, but has a high-risk. Gold is kinda stable if you want to do it safely. While in banks, there's a case where your bank face bankruptcy and it is a real problem once you meet this one, and also in banks it has a low rate compared to Bitcoin and Gold.
