My worst experience is forgot my private key and json file and stupid me i don't back up my important file in email. But after this case, i becoming be more carefull about all of my investment stuff.
it give us great lesson why every document from cryptocurrency market have to back up in safe place and not in single place,we must store it in several place.
Its true experience teaches us many lessons. In the starting, we all make many mistakes because of a lack of experience. I also started Crypto in the year 2017 I also had several coins that rises beyond my expectations but I hold it and expecting more profit but things happen opposite to my expectations. Due to greed, I lost huge money of my profit that I can book If I exit at the right time but this is what I said the experience I gain that will help me in the future to decide when to exit.
experiences in crypto market really need expensive cost, loss in trading or due our mistake didn't back up private key be commoin mistake at that moment . But now when we have more knowledge this mistake should not repeated.
