That will not work because cost of mining is close to $5000 falling below $5000 will a difficult situation for miners. We all see the balance this bitcoin was trying to keep in other not to fall below $6000. And now today we see a jump of $500 balancing it up to $7000. With time will get back normal or stable. If once it can cross up to $10,000 the bull run will start proper and those who get involve when it was cheap earlier will smile and be grateful for the decision they made. If you have not done so before, there is still chance for you to buy down and rejoice later.
