Many coins should not be touched now, especially those in the observation zone. Even if you want to buy them, you should buy and sell them quickly. Otherwise, if you are unlucky at the beginning, you may encounter the official announcement of the delisting of the coins you bought. It will be very uncomfortable. It is recommended to buy a lottery ticket. Just like $VGX , a delisting announcement directly caused a 40% drop. Who can bear this? So be cautious in everything.
