Now is the time to buy altcoins while the price of the majority top coins in the market are not moving yet as often according in the chart graph. As you can see the resistance is very smooth and we know that anytime it can suddenly pump and dump the price more where it could be after a minutes, seconds, hour, day, weekly or weekend.
I always feel when the market is subdued, it's best to either stay away from investing too much or just buy Bitcoins which we all know will never become zero, unlike other coins. That or you can buy solid coins like BNB or ETH because they have a real use case and tokens are built on them so they won't collapse overnight.
i still go with the basic buy at the dip and sell when its peak. With bitcoin and altcoins, for me it still works. But there is higher risk when it comes to altcoins particularly for new projects as they tend to have high potentials to have higher value at first, but when the market suddenly dumps, unfortunately most of them did not recover again.
It's almost as if the market has been divided into 2 sections. The ones who like high volatility trade new altcoins and the ones who are serious investors or traders and cannot afford to risk in the volatile altcoin market are sticking with BTC or just known alts that are in top 20 in the CMC.
