Both are important in our life. Bank is for keep our money in real life and bitcoin wallet for keep our bitcoin at online. I prefer pick both bank and bitcoin wallet because i use both.
Yup both are important in life for us who uses bitcoin , and also for me because i use bitcoin wallet where i can stock my earning in bitcoin and i use banks where i can sell or the buyer can deposit my money because here in my country our bitcooin wallet we uses are partnered in some banks where they can easily deposit our money
