There’s no wrong if you chose putting your funds in the bank for long term, that’s actually your choice, but never expect that your funds will continue growing, instead expect the opposite. Fiat will depreciate, while bitcoin will continue to appreciate its value, so do the math wisely.

However, I don’t encourage anyone to withdraw all your funds from your savings account, at least leave some percentage of your overall money, for your daily expenses, for your leisure time, and most of all for your emergency funds, the rest put them all into bitcoin.
