Increasing your portfolio during the bear market is advisable and everyone should really do this why you can see. Why is it advisable? most of the coins are being dump and that's how you become greedy by buying those coins at the lowest that you can get. And when the market's up it is the start of selling.
I think ita depend not all have funds to do trading on a beariah market. Im a trader and even though I have enough knowledge about trading isnt enough to totally ripped somw profit from the market. Still always on a case to case basis. Some alts right now are hard to understand. Whales, manipulating the market about your prospect coin to trade really affects the depth analysis when it comes to technical analysis. Id win some 10 to 20% from scalping but sometime loss is inevitable when the marlet moves fast.
