Many coins died in 2018 after bears trampled on crypto market, the end result was devastating so much that many coins got dead in few months, I'm positive that the next bear market will kill many projects too, weak projects aren't meant for bear season, to stay alive will be very hard
Projects that will die during a bear market are not strong projects so there is no need to worry as long as we still choose projects that are very strong in the crypto space, so the bear market is not something that anyone should be afraid of as long as we know when to let go coins we once held, and bought back in bear market conditions.
