Saving money in the bank and investing is risky, nothing is perfect and absolutely safe. Banks are centralized and may face bankruptcy resulting in frozen or even lost funds. Invest the bulk of your funds in Bitcoin and save for an emergency fund. Holding Bitcoin for a long time can look forward to one day earning more profits.
Yeah, nothing is perfect but saving money in the bank is safe IMO. Your money is there being held by there and being kept to their vault, while them, they're going to use it for funding other borrowers need and they'll take more interest than you, the owner of that money.
We know how their business goes but you have zero risk in keeping your money in the bank until something wrong goes on.
Just like what happened in Lebanon and China, their deposits can't even take their money because that's what the government says so. And for you to avoid that, it's better for you to keep it on your own and just as we keep our bitcoin, you're also the one to hold your cash.
