You have researched a lot because the above-mentioned coin is actively increasing their prices in the exchanges, which most of the coins have an active development team and it will surely help your portfolio to increase its value in the coming days easily.
the current growth situation is largely due to the increasing bitcoin market. I don't think there have been some successful developments that are paying pumps for their assets. right now I think investors and traders are also focusing on market analysis.
Altcoin has long been seen not able to grow properly, for many reasons, of course. especially for new altcoin there are no recommendations to be held before analysis properly, whereas those that already exist in the market are also currently not as good as in the past. maybe the corona pandemic also influenced investors to stay afloat.
but I agree with your opinion that at the moment the top-ranked altcoin can develop because of the relatively good bitcoin movement.
bitcoin obviously really affects altcoin, we see that bitcoin stays in a position around $ 9K, this really helps altcoin.
