you can buy one used car with $1k, which are only 4 btc with 2k already a better one, would be 8 btc
they are easy to earn with signature or real job, if you want to buy
I don't think it would be easy for him to earn like with his current signature and also his current rank , if he will consider joining to another campaign (like bit x for example) then he will probably earn more depending on how active he is and how constructive he post still not easy
he could buy a bicycle while waiting for the money, i'm sure you cna afford one cheap enough, in a month or two
Do you mean bitcoin price will rise that much in a few months?
