in my point of view i don't think it is kind of unsafest to me. for me bitcoin so far is a place for safe investment and a very easy way.
investments in bitcoin prove that bitcoin is the safest place to invest and to be able to earn more profits in the future.
because prices will continue to increase as time increases bitcoin users.
