Ofcourse it wont hold for a long time. The value is always changing. But you never know what is gonna happen. If it going to rise or fall.
We all hope that it will rise in the future, so we can sell it with a lot of profit. But we have the risk that you can also lose money if it is going to fall.
Currently, it is just going to rise. The only reason for it to remain above 700 is halving, and you will see something big whether up or down, before this happens.
