Yes it's safe to invest in bitcoin now, many are keep on saying that we are in a bubble but we're not really into it. If we are on a bubble now, when it burst the price can go down up to $1,000 again but no we are in real demand as many people are into recognizing the potential of bitcoin. You are worried about the bubble but others are worried about the peak price of bitcoin, so you better invest now while we are not seeing $10k.
