I always believe that bitcoin will last forever, it has come through a lot of difficulties, at times it is believed that it will die, however, it is still alive, and it exists, it grows vigorously. And reaching the top in the last few years, there are many things we can not say in advance, but we can believe in it. However, I am very worried about the bitcoin at the moment, it is facing the risk of crash, BTU may be crowned, but its value will not be equal to bitcoin.
