I use low fees if I'm just putting away some bitcoins into cold storage or transferring to other wallets. By low I mean 100-200 Satoshis/byte, never under 100. They usually confirm within 24h so I suppose I could go lower if I wanted to but waiting weeks seems silly.
bitcoin is a kind of currency in which people are getting a lot of benefit althrough if they are earning money through online business or either they are investing in it bitcoin is giving profit to all of us i'm very sure that it depend and how fast a user want the money by bitcoin because spending a more than a couple or year income just so another user can get they are not doing it smartly a lot of people are here who are using transition with low fees and mostly with no fees with no fees transaction would take half a day to get completed being in hury is never been a good and smart option.
