You have explain your understanding of crypto trading which is the buying and selling of digital asset. You have also stated 3 concepts that every trader needs to be aware of and they include setting SL/TP, the 2% rule and they fact that you don't need to panic when trading. Crypto is very volatile hence the price is never stable. Traders should always be informed about that and hence not to be scared whenever the price drops. I wish you success my friend.
