$RAY has taken off, and the original plan was to take profit at 0.211. Later, $SOL kept rising, so we will keep holding on. $RAY is the DEX on the Solana ecosystem. We can find an ecological development, in which the Defi track is the sector that benefits the most. Can we use this method to judge the booming development of other second-layer chains such as $OP $ARB in the future? When arranging the main chain tokens, buying the sector leader of its ecology will also bring good profits. For example, $SNX $Velodrome on the OP chain and $GMX $RDNT on the ARB chain, etc. Of course, all of this must be under the premise of the rapid development of the main chain. The above is just a personal opinion, #DYOR
