IN 2011 I was a online keeper. the first bitcoin wallet i used charged me 0.001Btc and that time i was earning like 0.000003btc per 5min or something it was a lot of work to reach 0.01btc and finally payed them the fees after then i heard that there is a wallet called blockchain and i registered there and saw that they where charging just 0.0001btc :p and today i am using android wallets with 0.00005 satoshi fees.
