Don't recommend HYIPs and ponzi, people will assume you are recommending a scam but personally its really a good way to grow your bitcoins with much higher risks. Early birds only make profit on such programs. I am investing and growing some of my coins right now with HYIPs and with ponzis but I wont recommend it.
