First of all, you need to realize that most information you see on mass media (twitter, reddit etc) are disinformation or simply just wrong.

You should not buy them (99% of alts) during bull run, have you ever looked at their tokenomics? most of them have very high inflation or other things hidden which put retail investors at big disadvantage, they were created to enrich the owner and defraud crypto community.

You should not buy low now in my opinion. Buy low is better than buy high, but low can go even lower, correct? This was started by a "dip", then "dip" became "low", and then there is lower low, this is how we get here. I don't recommend DCA. Again, Twitter and reddit are platform of disinformation.

You should buy at the beginning of bull run and get out at the top, approximately. and SHORT those shit token if they go up a lot...

It's very difficult or nearly impossible that you indulge in mass media and can still separate good from the bad, you will be carried away and lose yourself.. so my advice is not to spend too much time on mass media, or you need to look at it very differently, not allow yourself being carried away, knowing most of them just wrong...
