In times like this which is more profitable having your coins for trading or holding the coins for long time?
It depends on your level of trading skills. Now you can buy some coins really low for long term, but if you know TA, you can do daily trading and make profit every single day. For trader it doesn't matter if the market is bullish or bearish - profit is everywhere)
Either both ways would really make you money if you do know how to deal with it but it wont really be an easy thing yet we do all know that short trading and using TA would require experience for you to find out possible movements of coins in the market. Volatility is on where most short traders do really love but if you are going for long term trading then its up to you if you do skip active trading.
