I invested many altcoins from last year. I was inexperienced and I lost my most of money. after that I stay away from altcoins I front the ranked coins and not stay on longish.In bear trend, I prefer top coins instead of altcoins definitely. many coins will gone.
The benefit of doing that is that you would not have to face troubles because the top altcoin are way too stable as compared to the others and in addition have more chance to grow in value so it is good to invest in top trend.
