Transactions can not be lost. If you do not lose you will not have much experience. Anyone who wants to succeed must have failed, and failure is a lesson to succeed in the future.
You are explaining about the experience how could we get success, and in reality it is true, we need hard working then we get a success. So same like in bitcoin, it is dump then it meant the big pump is coming. But bitcoin is digital currency and it is its quality that sometime it is dump and sometime it is up. In this wise, we get a chance to earn profit from bitcoin.
