I was optimistic about the coin $NEIRO at the beginning, so I bought the spot. Later, I did the contract and didn't buy this. I bought celo sui ena Neiroeth. The last time the contract almost exploded, the reason was that the position was too heavy. This time, the spot was changed to the contract, and the spot felt too slow, so I entered the contract. It took 2.3 days to make 19,000 u from 7000u, which was inflated. I bought several coins at the same time. I paid special attention to Neiroeth again. I saw the market maker enter the market, followed the entry, and did make a lot of money at the beginning, but then I gave it back. Now I understand that market makers can indeed push up the price of coins, but a few market makers control 10% of the shares, which has formed a banker. With the associated addresses, they sell high and buy low, and play around with retail investors. This time, the position is light, but I bought more coins at the same time. Although it will not explode, my mentality is already unstable. At this time, the position has become 6000u, and the original entry capital is 1000u less. The lesson is: light position, only buy one coin, don't follow the trend. Stay away from coins that are highly controlled by the market makers. I am still optimistic about it later, sui cell ena Neiro. Come on! I wish everyone good fortune!
