I think the more popular Cryptocurrency becomes, the more regulation and government scrutiny they are likely to attract. Also remember that Cryptocurrency has no intrinsic value(value of a company, stock,currency or product that has market value) apart from what a buyer is willing to pay for it at a point in time. This makes it subject to huge price swings, which increases the risk of loss for a investor. Just make sure you can stomach this kind of action as a investor though.
