No matter how good other projects are, bitcoin and ETH will always be in the top two on my list. If i am going to invest in any altcoin beside ETH then it will be a new one that came to the market when the market was in a bearish moment. Also it needs to be a new narrative that can be in the next trend. From my observation, I saw that you will make money in the altcoin market if you follow the trend. When there is a trend going on about pow coin or pos coin and layer 1 or layer 2 blockchain then more people will start investing in those projects with FOMO. This will cause a pump and all the project in that category start pumping hard.
