A friend of my want to give me 3BTC and he want me to pay him back 4BTC in 2month 7days but he asked me what will i do with it, how can i turn 3 bitcoin to 4 in 2 month 7days, what is the best investment that can give me good ROI in that short period
So please i ask for your advice
The only thing you can do for reaching that target is trading altcoins but only if you have enough knowledge about it, otherwise you will just end up losing everything your friend gave to you, don't try gambling by thinking that you will double the amount in no time because once you lost them there you would never be able to recover anything so just stay out of it.
