I would pick that option also if I got a lot of capital but for now it will little by little. I know that bitcoin got a good future but the money needed to afford 1btc is really high. So take step by step and just earn something for better price someday.
Bitcoin can be earned in many ways, so I don't think that we should invest our money in buying it, instead make efforts in earning as much as possible.
Why not? It will give an impact to bitcoin. Imagine all of us are buying it simultaneously it will be a great increase for its value. Okay earning is a good way but not a faster one. It is a good addition for your investment. Those who pays for an online job paid thru bitcoin are buying it for us to earn and I think they got a much profit than us although they didnt really do it for that reason.
IF you are just buying bitcoin when the price is high 700 value or more.. i think you can not make a profit but you can hold it for a long time to wait for 1k value.. so that you can make still profit and no lose..
