As much as we tell people to invest with Bitcoin but not with borrowed money. With this, you can't have that risk to take and you're paying off together with the interest once you take it. And as you hold bitcoin, there is no assurance that you're going to have it asap and withdraw it in profit. But if you can take that risk and you know what is happening and the thought of yours is wanting you to push for this, who are we to stop you? Although the best thing for you to do is to DCA, dollar cost average. Buy every single time that you have some money.
