I will advise you buy bitcoin based on your projection of it's price over the next 10 years!
You know many people who fear to invest in bitcoin do so because they are thinking that the price has gone very high per one and that it won't rise again abovr such and they want to look away but the price does better each time it starts for bull and going above last ATH and creating a new status. This shows that bitcoin is just in starting point and has yet started to increase. Things are different now, the level of education and adoption is not the same in 2017 and this is why that the price will keep going up the way I feel
Knowing the mainstream media articulate always the risk of crypto rather than giving some good news on it for sure people will think about negative when it comes on bitcoin or crypto. But for sure once they see many people change their lives due to their risk taking on crypto for sure those who doubt will go with it. Although they will face failures but once they learn about this they provably recruit and make their friends use bitcoin to.
