Unfortunately, many crypto projects failed to make in through the last 2018 bear market, I believe the same thing will happen this time too, the 2018 bear market lasted till 2020 after the CoVid 19 outbreak, we aren't expecting that collapse but it happened and Bitcoin was affected big time, though the crash doesn't last very long, many quit investing and believed that it's over but those who are fortunate to invest in that crash made the biggest money through crypto.
Many people believe in Bitcoin as the most valuable of them all, even after the 3500$ crash many whales still held their positions, as if nothing is happening, they knew that these tough times would pass and they are right, those who are not strong enough sold their Bitcoin and left.
