This idea sounds like Forex which is where its common to take a bet on currency direction, short Dollar to buy Bitcoin. In the case of vice versa short BTC to long dollar actually pays some yield, any currency measures by the difference in interest rates available. To go long BTC requires a very bullish attitude and alot of skill to be correct on direction, in any case the point I wanted to say is Forex traders are usually very short term because its such a tricky volatile market to speculate on. They spot a trend, they take a trade and they close out on the objectives for a profit. I dont hear many doing the same long term.
Its an advanced topic and really its not advisable for anyone outside that set of skills, artificial leverage like this is not helpful and most people are already extended in some way without realizing as most of us arent rich.
since I still have another source of income.
Thats an assumption going into the future, the possibility would be that the strength of Dollar rises at the same time businesses cut back and unemployment rises, its a nasty situation thats happened before. People who have taken loans based on their previous circumstances are then in trouble, it'd be fine if BTC rose in this economic outcome but I think it would be challenged at this time for at least a while.
Leverage and crypto are like oil and water and best not mixed. Its actually smarter to buy over time and distribute risk, I think its an established method actually:
