Bear market is a great opportunity to invest, when bear market comes i only invest in some well known altcoins, it doesn't matter if it is new or old altcoins as long as it is proven and tested i will buy it and hold till bullish market back and sell them to get profit. There are some new altcoins that has a potential and there are also proven  and tested altcoins and they are now easier to pick because they are listed on some crypto currency tracking platforms.
