It depends on where you are located. Saving your money in your bank is an easy option but not very lucrative.
In fact, I have read an article about banks who are going to charge negative interest rate on your savings account. Which is ridiculous of course.
I would choose for spreaded investments. Leave 70% of your money in your bank, and invest 15% in Bitcoin and the other 15% in something like a Bitcoin startup.
I like how you take care of your money but i myself won't save all my 75% money to bank, i'd better out 35% to bank if you have lots of money or not too much but i would save 35% money to bank and 35% to myself and the 30% money will be for investing in bitcoin. According to what i heard from someone talking about money they split their money in portions so in case of emergency they have money to use and the money you save won't be touch. Example 20% daily needs and wants 25% for bank 25% for emergencies and the rest for bitcoin of course if you can carry the loss if it happens.
