I think that can destroy bitcoin is a person who participates to bitcoin itself ,, just as bitcoin will be destroyed if bitcoin users use it to do evil, then the world will see that bitcoin is bad in the eyes of the world, then also the mining beyond the boundary can lower the value of bitcoin currency ,,
and there are many other things that can destroy bitcoin ,,
and hopefully we do not include people who damage bitcoin ,,
There is nothing that can destroy bitcoin so stay calm and invest as much as you can that will bring fruit in the near future and you will be among those who are the profit scorer. An in past many people want to take down bitcoin but bitcoin is still up.
And it will keep moving upward. In past many of organization wanted to destroy but now they are using bitcoins.
