I hope I can do that too. I am saving just for the week then withdraw it for bills payment and things that needed to be bought. I got a day job but it is not enough for the month.
Good luck saving.
How i wish too that i could able to save up all my bitcoin earnings but sadly same as yours i need to cash out them and exchange them to fiat for my daily needs and expenses ,i do also have a job but the salary is not enough thats why i actively spend all my bitcoins which is somehow a very big help for me.
Yes if we are earning it then we should also spend them when we are in need of money and there is nothing wrong in it as we can always buy it again and save it for future.
