I think we need to always be careful on buying not only today but also in every season or market condition, not all alts are affected of bear market during bear season and not all alts also affected during bullish season. Because everything depends on the projects backgrounds and team behind it together with the developing team. That is why expert always says always do your own research for good.
I agree because in bull market, even bad project find a way to raise their price but we need to make sure we check the background of project and not only focus on the price trend of last weeks.
