Every investor is ready and willing to take risk, but a risk that is not worth taken is a risk without result, as for Bitcoin, the risk is worth taking, but for long term investors, who are ready to wait and see a transforming growth in their assets. Bitcoin in price is worth investing, but don't be deceived, as the price can increase and decrease with a 10% or more within hours/days, and this rollercoaster ride makes the shaky hands drop, while the experienced fill up bags.
To me, Bitcoin is a thrilling investment and a risk worth taking to have/gain financial freedom, if well used and managed.
