Most people buy high, HODL, then sell low.
Bitcoin could be a win-wim situation. What really is your capital is not the money that you have but the brave heart the you need. It is all about the risk knowing that somehow it could lead to regret. Now, if you feel like it is the right time to buy, then do so. It is worth the risk anyway.
Everytime is the right time to buy a bitcoin. But it will depend on you if you want it too. But for me the right time to buy bitcoin is when the price of this will drop because you can save such a great amount of money if you will just willing to wait for the right time. But it will depend on you if you will buy bitcoin in such a higher amount..
