I do not spend or deposit daily in gambing sites.Well it depends upon the amount of bitcoin i have at that time or my mood as well.But if i have to say on average then i think i spend about 15-20 usd weekly on gambling or doing sports betting.
me similar.usually i'm betting with low amounts and on websites that are offering low bets and high faucet 
sometimes when i'm feeling lucky i deposit up to .1 btc and try to double it and the withdraw.
