Seems you have not Heard about the DCA strategy, if you're finding it hard to invest in lump sum why don't you stick to the DCA strategy..... with the help of this DCA strategy you don't necessarily need to figure out when and where you're going to start from but to start buying as much as you can every week without paying attention to the market condition, I think alot of guys have no idea about this strategy which is why they feel that they are not qualify to go into bitcoin investment but that's wrong, there is no fix amount in bitcoin investment you have every right to invest with any amount which you know it can be easily afforded so as to enable you maintain the ongoing buying of bitcoin until you get to a point where you feel that the amount which you have accumulated is enough for you.
