Lack of sources of income is what is causing some new investors to borrow money or take out a loan to begin investing, if you have a reliable source of income, as a new investors you will be able to save for emergency funds without having to plan for it before investing. It can also help them to prepare for DCA strategy.
You can sell a dormant property to invest in Bitcoin especially when you have somewhere you can stay or the proceed from the sales can afford you a decent rent in which your future cashflow can cover, while you put the surplus into Bitcoin. But what I can never support is taking a loan to invest in Bitcoin because that will mean investing with money that is not yours and this will put you into pressures to even sell your Bitcoin at a loss when the loan maturity reaches and you have not realized good profits. The ideal thing is to always invest with our discretionary income which loans does not fall into, hence my reservation to taking loan to invest in Bitcoin. Assuming you take out a loan of say 4 years and buy Bitcoin. The loan plus the interest is something big that you don't have the guarantee that the Bitcoin will give enough profits within that 4 years to pay back the loan with the interest.
