i think does not have the best time. If you have money now you can get it.Because nobody knows what the price of bitcoin will be after five years. Maybe you can be rich after years. 
Nobody knew the value of bitcoin five years ago.look now.
you have a point there buddy. that's what I'm thinking when talking about bitcoin there's no assurance that we can get rich after five years so why just don't believe in bitcoin ? right ? because after 5 years maybe you will be rich . so invest now until it's not over $3000 per bitcoin. but even I'm encouraging you all to invest now maybe you could wait until it's under $1000 before you invest in order you to feel the successfulness when it comes on bitcoin investing. Nobody knew the value of bitcoin five years ago.look now.Waiting bitcoin price down to $1.000 below was the same to you when investing in now time, why? because the both option made you wait for long time or even short time we didn't know when the bitcoin price go up and down, there's a chance when you leave for sleeping bitcoin price may up/down $100. Invest when you patience enough to accept an unknown conditions.
