Investing in Bitcoin with long strategy spanning 3 years is a good and prudent approach, provided you have sufficient source of incomes to finance your monthly installments of loan. However as we are all well aware of that all financial markets are volatile and in particular Bitcoin which can potentially fall to the extent of 80%, as shown in its historical trends. Therefore , success of your plan will largely depend on your ability to continue funding your loan installments and Bitcoin market market movement in line with your expectation within next 3 years. It would be wise to carefully consider all risk factors before making investment decision.
Off course investing in bitcoin with spanning 3 years is good approach if the op has strategy. But i think the OP should build more precise strategy because during 3 years investing, many things will happen to his investment. His investment's value may drop or increase, so the OP should always monitor the movement of his investment.
