2. Buying alts when the markets in general isn't necessarily a bad thing when talking about trading, because buying at rising prices with high volumes is a thing that could be taken advantage of.
Yea it's true buying when price is rising isn't a bad idea because there would be enough trading volume and also high volatility which could fetch enough profits, but when this becomes bad is when traders or investors buys at the top which is really very risky because there could be a big correction which will cause loss to people who bought at this point, and this is where people really get emotional, because not everyone can bear the pain of seeing his capital depreciating.
