i know bitcoin itself is already an investment but i have 3 bitcoin sitting around and I'm looking for a quick 5% flip any idea??
You don't specify how quick 'quick' is, or your appetite for risk. These are the 2 things you need to know when investing.
Do some research on HYIPs if you want it today and are willing to risk the lot. Or try peer-to-peer lending, pooled investments, and margin-funding if you want to learn some investing basics and slowly work your way up to solid returns for the rest of your life.
But always remember the basic rule of investing - if it sounds too good to be true, it is!
