Believe whatever you like, but bashers do 10x better DD than pumpers.
When pump is working go ahead and get onboard.
But realize pumps are short-term phenomenon.
So when the volatility sets in and the chart is no longer uptrending and everyone is saying to "buy these cheapies", you should stop believing and get the fuck out of the position!
You can always get back in, but there's NEVER EVER EVER a reason to continue believing and holding onto a downtrender (or add to a losing position) unless you have inside information... which you don't.
