That is the best decision considering the situation at the moment because you cannot be investing and continue to sleep with hunger. But the greatest mistake that the OP made was to make a proper preparation before embarking on the journey of long-term investment. If he/she has another source of income, he/she will definitely profit and achieve his aim now that bitcoin is 69k to 70k. That is why the best way to do long-term investing is to keep a good strategy. 

But it is based on economics that he/she will be encouraged to continue borrowing the money as long as the money he/she will be borrowing does not exceed the limit. It will be the best since he has already put it as his project, so the main focus is not the borrowing of the money but achieving the aim, and if we go with that, then he/she will definitely achieve that aim. Buy now because the rate of bitcoin is high. That is the power of hard work and the power of money.
