The amount of money that the investor has left can be invested in Bitcoin with a part of that remaining money, hopefully if the investor invests in this way, his investment will not be irregular.
The remaining money left can instead be in bitcoin and not necessarily as an investment, because we may need to use it anytime and that will not be a disappointment on us selling at unprepared time, i know bitcoin to be of a profitable asset and there is much possibility of making more profits if we have our assets, investments or any money for upkeep in bitcoin, because we are having control in it and are in full custody of what belongs to us, not only this, we still stand a chances of earning more as the market provides volatility and by this we can earn when it rises.
