Okay so i understand that all bitcoin i receive is taxed as income and then taxed for capital gain once i sell but say this happens- I loan 10 bitcoins out and then at the end of the month i get 11 bitcoins back with the 10 being my principal and the extra 1 as interest. would i only need to pay taxes for the 1 bitcoin since i payed taxes already on my other 10 or is there something wrong with my assumptions?

I have a loan on btcjam that i'm going to pay on Wednesday then afterwards i want to open another loan with a 1 week term and a 5% interest. you can check out my profile with the link below. I'm asking so that i can know how much i can ask for. if you guys have any questions please let me know i'll gladly answer them.

Hi everybody i really hope someone could help me out with this situation. I know that i have to pay taxes once i cashout my bitcoin (shame i have to do so, I'd rather buy stuff with bitcoin) but do they tax just the capital gain or the whole price of bitcoin? Ex. I bought 1 BTC priced at $400 then i sell said BTC at $450, Do i pay tax on the whole $450 or just the $50 profit i earned?

Also what about mining? like if i mined 1 BTC that was worth $450 the day i mined it, and and then sell it at $490 do i pay the whole $490 as income tax and then another tax for the $40 profit as capital gain?

Someone please help me out as i am confused with all this nonsense.

I would like to develop a site similar to bitcoinera.net, i have stable investment opportunities and plan to last forever. However due to the intentions of lasting forever 6% a month is not possible. I intend to have my plan at 2% a month. but what im asking is how can i get started?
