Okay, you got some pretty much source of income here which is you can gain your capital easily to hit that number. I still do not get it how you are going to make that much in just a short time, anyway it is really a good job you have there by slowly gaining money and stack it there
it wasn't exactly that short and I have a LOT of ways of making bitcoin. for instance I recently received 0.01
BTC payment from the ads (banners) that I had with some bitcoin ad network that I don't even remember which one it was, I just know the address that received the payment was for ads.
there is also my signature campaign payments. looking at my payments I currently have 0.45
BTC which is for more than 3 months of work.
there is also trading. and sometimes I get lucky there! for example I earned 0.1
BTC from some shitcoin that was getting pumped and I just joined the ride and transferred the profit here.
I even have some plans to start some mining operation. possibly will start it in winter.
the thing is, I really do believe in the future of bitcoin so I am busting my ass earning as much as I can and also from time to time I buy bitcoin with fiat to accumulate more.
